MY husband and I did ok in general, but I remember one particular night when DS1 was about 6 weeks old, maybe younger. I'd been struggling with breastfeeding (hated it) and I think the HV had been round and criticising me about it (she did that a lot, I stopped seeing her fairly soon after that). So I was not coping well.
DH came from work, and to give him his dues, he cooked the tea and cleaned up etc. Then as it was Monday, he had football practice. I asked him not to go as I was really struggling, pinned to the sofa by the never full baby. He suggested we gave a bottle. I caved as I was so sick of breastfeeding, and we did. It was like magic, the kid seemed content at last! HV had dismissed any comments about bottle feeding up to that point and as he was my first and I was clueless, I didn't dare give him a bottle in case I got into trouble (madness looking back, but you can't see through the fog at times!).
Anyway, he then announced that as the baby had settled down, he was going to football, but it was ok, it was only an hour and as soon as he got back, he would help, he would stay up with the baby and let me sleep for a couple of hours.
Except it wasn't, because it was about a 20 minute drive away, plus he needed time at the other end to get ready. So half an hour, hours practice, half an hour back. That's two hours. Then when he got back at about 9.30ish, he couldn't do anything he'd had a shower. Another 15 minutes (he is incapable of a short, quick shower - still drives me to distraction 7 years later!), plus then he needed some food and a drink. So it was more like 10pm. He then offered to take the baby. Bit late, I'd gone to bed. Refused to let him in the room, he had to sleep downstairs.
He genuinely didn't see what he'd done wrong, he'd offered, and totally meant it, to take the baby to help. Except I needed the help at 7/8pm, and by now it was 10pm and gone, and I didn't need the help anymore, I'd struggled through on my own.
He did listen though, and if I asked him to miss training or whatever after that he did. We got through it all, had DS2 and he was great with it all.
But that one night flagged up to me how easy it was for him to walk away from it all, and I knew I needed to do something to make him see that he couldn't do parenting after his hobbies, parenting was 247 and we both had to make sacrifices.
