Oliver so sorry about your DP,I I hope your both getting some support from friends and family.
My life is as far removed from your friends as possible I think,we have 5DC and 2 of our DC and myself are disabled.
We don't have any back up or support at all,were the one's that are looking after and sorting out things for my Dad who's disabled and seriously ill now despite one of my brothers and nephews living with my Dad.I end up going up there and spending an hour or two tidying up,cleaning and picking up after all 3 of them with my Husband and not surprisingly my DH is fed up with it,he doesn't mind doing anything for my Dad he loves him and he loved my Mum,he just hates the fact that I'm doing it instead of the two men(brother and nephew) that could do it.
With the starting jobs and keep getting called away could the children not come to you?I used to always go to our 5DC when ever one of them called me but I had to stop when I became disabled and my health started getting worse.
I'd hate having to start and stop all the time and I know I would loose the momentum and end up getting sod all done.
We've got the broken sleep nearly every night as well,our youngest DD8 is autistic and has a lot of health problems and some physical disability as well,she can still have months and months of sleep like a newborn,we still have to use a baby monitor for her and I can't see that ending any time soon.Our oldest DD12 has started having fits at nightime,not every night thank God they're horrendous when they happen to her and we have a sleepwalker DS17 best one ever was when his Dad caught him climbing into his wardrobe trying to stick his legs through a sleeve and the head hole of a jumper and insisting he was putting his tracksuit bottoms on
and not having a clue what his Dad's problem was with this,that was at gone midnight.
Your not alone Oliver,if you ever feel like you need a hand hold I've got one spare. I hope things start settling down for you soon.Fingers crossed for you that one day the only thing you'll have to worry about is your DC waking up before 7 am on a weekend,I've still got my fingers crossed for that day for us as well
