It's hard. It really is. I only had two dogs (staffs - aged 4 and 5 then) when my DS was born and it was harder than I ever thought it would be. A lot of it was the guilt that I couldn't give them the attention I did before, the baby took up SO much time, more than I could have imagined - I was breastfeeding DS and as much as I loved my dogs I didn't want them in my face when I was trying to do that (and learn how to position, get a decent latch, etc).
A poster above mentioned floor time and I found it impossible to do this happily with the dogs in the room, they would want to put their faces into his and generally trample him with excitement, to be honest they ended up shut in the kitchen and this made me feel even worse.
Walking the dogs became DH's job exclusively as I was always breastfeeding/trying to catch up with sleep and it was hard on our relationship as we had always used our dog-walking time as a chance to talk and connect. I did have a sling which really helped in the days when DS was small but as he got bigger and heavier it was more comfortable for me to take the pushchair, I couldn't take the pushchair to our favoured dog-walking spots (mud, stiles, generally unsuitable terrain saw to this even with an off-road buggy, it was difficult to handle alone) and the dogs became frustrated with a rushed walk after DH got back from work, as obviously he wanted to spend time with his family - we did have lovely walks together on weekends, but again, the guilt was immense - I loved my dogs so much, their lives had changed a lot and I felt it was all my fault.
As DS got more mobile, it became apparent that one of the dogs had a real problem with him and was very uncomfortable around him. I had done all the preparations, got the dogs used to a baby (by carrying around a bloody swaddled doll!), got them off the furniture, stopped them sleeping on the bed well before DS was due so they wouldn't associate their "eviction" with him, played CDs of baby noises/crying, walked with an empty pram to get them used to it on walks, fitted stairgates everywhere, DH brought home a blanket we'd wrapped newborn DS in so the dogs could get used to his smell before they met him. We did everything right and yet there was a clear issue with DS and this dog. Eventually a friend of mine took the dog on as we realised (with some expert advice) that the dog was not suited to a family like ours - he preferred being an "only" dog, and that was fine as he is now much happier with his new owner (he has been there over a year now, DS is 2.7). I know other Doghouse posters will disagree with how I resolved this but it was a truly horrifying, awful situation that you can't imagine being in until you are, and I have to live with the guilt that I couldn't fix the problem. Older dog is very happy in his new home and getting the attention he deserves, but he was very lucky that my friend loved him, knew he wasn't a "bad dog" despite his behaviour with DS, and chose to take him on for life. Staffies who have shown undesirable behaviour towards children don't often get a second chance.
Basically, what I'm saying is that there was a lot of heartache involved as we realised we actually couldn't cope with the situation despite being so determined.
Our other dog is still with us and actually the rehoming of the older dog was beneficial to her character and personality, she is now the laziest thing in the world and likes nothing better than snoozing with DS and the cat. We are not stressed trying to keep a dog that isn't happy away from a curious DS, and life is generally easier. The dog and DS are best friends and seeing them play together is a joy.
I'm not saying you should get rid of the dogs, and I'm not being patronising but it really will be harder than you think.
3 dogs (and 2 dogs) is a pack. One dog is a dog. There are lots of things to consider about dog psychology (seriously!) and how to deal with unwanted behaviours with/around DC. You can't say you know that your dogs won't display any because a) it's impossible to say with ANY dog how changes will affect them (my dogs were perfectly lovely with people and all children, they were boisterous yes but perfectly lovely - however when it came to living with one 24/7 things were quite different) and b) they are still very young - their personalities and characters won't be fully developed.
Again, I don't mean to sound patronising but you're 22. I was just 20 when I got my first dog (the older one) and although I was 25 when I had DS so the dogs were a bit older than yours, I felt like I was out of my depth despite the love I had for my dogs (and child!). Staffies are a very boisterous breed and need lots of stimulation, constant training and exercise. I can't speak for huskies but I imagine they are quite an energetic breed too given their history. You need to be prepared to literally NEVER do anything for yourself. That's what it's like. Bringing up a small child and 3 young dogs is a 24/7, 365 day a year job.
Where did the 8 week-old staffy come from? 8 weeks is quite young for a pup to be removed from her mother, what's the story here? I can appreciate how maternal and hormonal you must be feeling but is it REALLY a good idea to add to your work by taking on another pup? I realise she is with you now but there might be better options for both you and the pup. I don't doubt you will love and adore the pup but it will be a real strain on you. Don't forget that dogs have terrible twos too (well mine was more like "terrible 18 months - the "teenage rebellion" as I referred to it
)!
Did you get her from a breeder? Was the breeder aware of your situation? If I were a breeder I would not allow a young, heavily pregnant mum with two young, high-energy breed dogs, to take one of my pups. I wouldn't.
I reiterate my point above about staffies not often getting a second chance. I'm not saying she WILL display undesirable behaviours around DC but having 3 dogs AND a baby may turn out to be too much for you, and if you realise this after a while, she will have less chance of a happy ending if you leave it till later to try and rehome her. I am not suggesting you would, but just telling you what I know about staffies in rescue, etc. An 8 week pup has a very good chance of a happy ending in a suitable home.
Again, I honestly don't mean to be horrible and I have no doubt that you are a perfectly capable dog owner and will be a lovely mum, but you asked for the truth about dogs and newborns, and the truth is it was one of the hardest periods of my life and not one I would repeat in a hurry! I'm not saying "give up your dogs" - far from it, I think it is lovely for kids to grow up with dogs and my experience is probably marred by the problems we had with DS and my older dog - but do think carefully about the pup. Talk to the breeder if that is how you obtained her. There may be a more suitable home out there for her, and you will be lessening your (already large) load by a quarter. There are posters on here involved in rescues who can probably give better advice than I can but my point is to just think carefully about what you're doing.
I truly wish you the best of luck, and I'm here if you want to PM me for a chat. :)
