When I had DD1 my life changed completely, at any moment, no matter what I was doing I might be called upon to care for someone else.
DH had a fortnight off work during which he caught up on a lot of DIY, as he put it you can't just stare at them all day.
What he did n't realise was that the only way he could disappear off to the shed was because I was close by to feed/pick up/sort out the baby when it cried. And of course you have no idea whether this would be in 2 minutes or 52.
DH never realised how exhausting the nagging responsibility that being constantly in charge can be. He is a kind man but just never got it. He'd start looking after them but if they were quiet he'd drift off down the garden or get on with a job that needed a good three hours to complete. Once again I would be responsible since I was 'only' having a bath or reading the paper or he'd jump at the chance to take the dog for a walk and combine it with 6 other errands.
I am still bitter about how he treated me and how the issue was never solved calmly but used to envolve a minor break down every 4 months.
When it goes wrong, it does go wrong. When DD1 was 4 years I had to be emitted to hospital with a suspect brain tumour, kept in over night, scanned etc. DH was worried about me and utterly hopeless. Brought the kids to the hospital with nothing, no toys, nappies, food, charged mobiile phone etc. So even at that point, I was pressurised into 'organising' the family and discharging myself inorder to to go to one of his families wedding.
The conclusion was the whole thing was brought on by stress.
It is easier now DDs are 6 & 4 but unless I book myself into something out of the home environment I still end up worling 24/7 and DH always trys to involve other friends so that actually other mothers have to remember snacks etc.
Well that's all about me, did n't realise I was still so angry. Organise something, if they don't volunteer and you're always there build something firmly into the weekend eg he always has them saturday pm.
