I think everyone’s experiences are really unique (which is obvious I suppose.)
When I had DD, it was a lot easier than when I’d had DS. She was a very snoozy baby and I actually understood in a way I hadn’t with ds how people got to watch box sets and just snuggle up and chill (of course I had a toddler but he continued three days a week at nursery.)
I wouldn’t say on balance either of mine are difficult children. Ds has come through a very demanding baby phase and unpredictable and sometimes thuggish (!) toddler phase to be for the most part a very chilled out, easygoing and pleasant individual. He isn’t perfect: he’s prone to being very boisterous and can get silly and manic easily; he can be destructive (not intentionally but like yesterday decided to bring a load of mown grass into the house because he was playing with his toy combine harvester - whhhhy) but on balance you barely know you have him.
DD is nearly three and more difficult to navigate - she can be very demanding and a
petulant; she does that toddler thing of saying the same thing over and over (‘I want drink’ yep I’ll get you a drink ‘I want drink; I want drink; mummy I want drink’ like FGS I AM GETTING YOU A DRINK!) but it’s completely normal and I’ve no doubt the next twelve months or so will steady the more infuriating elements of her personality and be replaced with some logic and reason.
Together the dynamics do change though, and I’m kind of hoping for the better but … more often than not this isn’t the case. Together they are much sillier, louder, wind one another up, encourage one another to do things they wouldn’t ordinarily do, like most siblings they aren’t always kind to one another and while I’m very clear we don’t tolerate name calling or eg hair pulling or hitting it can be difficult to untangle the threads and see exactly who started what. And managing that can lead to further conflict. So it’s inevitable to a point there is more shouting, crying, upset and general conflict than in homes with only one child. I know some people see this as a positive; I’m neutral. I don’t think it’s a bad thing necessarily (although it’s stressful for parents) but while I can see benefits to managing arguments and the like I do think children get this anyway, as it’s pretty much unheard of not to attend nursery or preschool.
I found last year, when they were both home with me for two days a week very hard and stressful; DDs nap was a big problem to be honest as she needed one but this meant days out were difficult; ds was loud and prevented her sleeping which gave me a proper red mist at times. More often than not we’d go out in the morning, DD would fall asleep on the way back and I’d be ping ponging between the house with ds and the car to check on dd. It’s easier now ds is in school but I do feel guilty that the year before he started school was so unenjoyable for me; I’d have liked to have really spent quality time with him. Luckily, dd continued to go to nursery three days a week in the summer holidays and I got to spend a lot of time with ds and I realised how beneficial this was to us both, it connected us again properly.
For the most part if I am honest I would say I don’t really enjoy parenting them together but yesterday they played together beautifully and I actually got to talk to the Mum I went to the place with! So there is light on the horizon (I hope anyway.)
But I guess what I’ve come to realise is it isn’t just having another baby; it changes your first child, your second, your relationship. Even friendships have been affected - most of my friends only have one child and I’m lagging behind literally and metaphorically as their lives have moved on and I’m still in toddler groups and preschool.
