I should be in bed as only got up to feed dt2 and update tesco order, but had to respond to this Bbeau.
YOu are really going through it, you poor thing, sounds like someone needs to give you a big hug and there's just no-one. I second keeping up with the lady in a similar situation, it will just be busyness for her I think, I certainly can't get on the phone very often these days! I have a 5yo ds, 2yo ds and 3 mo dt's (ds3 & dd). I have none of the health issues aside from recovering from spd. I have a homestart volunteer and she's priceless, she just comes around and looks after the dt's whils I have a nap, or tidy or whatever, comes with me to pick up ds2 from nursery. Lovely to have that support every week.
My first thoughts on your post were why wait until the summer for a nanny, you need one now if you can afford it. Get the help now, it will make such a difference, mother's help, nanny whatever, just someone for a day or more a week will change it round for you.
And I think your dh has to help a bit more with a regular chore(s), you can't do it all yourself. Why can't he get up earlier and make up some bottles etc? My dp gets up and gives the older boys breakfast every morning because I'm busy with the dt's.
I think the buggy will make a huge difference, I feel the same way as I can't leave the house with all 3 (the dt's & ds2 who is too young to walk v.far,he was a late walker). You'll feel much more able to do things should you want to and make the nursery trip easier. Ask the nursery staff if one of them will pop out to the car and watch the dt's whilst you drop off ds or come and collect him, my nursery are happy to help me out with car seats and I don't think you should be carrying 6 mo babies in car seats in your condition really if at all possible!
Can you find a small window in your week on the weekend maybe when ds napping and dh has the dt's to just go for a walk on your own, just an hour or two for YOU as it doesn't sound like there's anything at the moment. Really really important imo, more important than chores because if you fall apart and collapse one day everything else falls apart.
Re: dealing with a 2yo and dt's, I have a nanny here on the days that I've got all 3 of them as ds2 at nursery 2 days and my mum has him a 3rd day. So I don't have to deal with all 3 that often and luckily ds2 is very laid back. If you had some help and/or a buggy for all of them, I think getting out of the house would make it easier as he wouldn't be a tornado. If they're not there, the house doesn't need tidying, my five year old is exactly the same although at school now.
Thinking of you and hoping that things get better at least you can come on mumsnet and vent if that helps.
