DH and I have had a system, since DD was about 4 months old, that I cover any night wakings from Sun-Thurs and DH does Fri and Sat. I am currently SAHP with a small bit of freelance work, and DH is wfh. This is clear and never been questioned. We revert to taking it in turns every other night when on holiday and had a holiday over Christmas. But this week we have been back to normal with me on "night wakings duty" since Sunday.
DD is 18 months but having a sleep regression and nightmares requiring us to rock her back to sleep. I have been up 3 nights this week for a number of hours. Last night (Fri) she cried but DH kept sleeping. After I while I patted him and alerted him to get crying. He said it didn't sound too bad so he wouldn't be getting up. She got worse and worse until long story short after 30 minutes I told him to go and look after his daughter. (I know I could have gone but I just felt like it was his responsibility and it's not fair on me.) he then started saying that he didn't remember this rule about him doing weekend night wakings. This was utter rubbish as we've done it for the whole time. But he kept saying he wouldn't go.
In the end I was fuming and told him so. He went in her room and picked her up but she was screaming by now. After a few minutes I looked in and her had her sat up - as if he wasn't even trying to cradle her back to sleep. She saw me and called for me so in the end of course I ended up looking after her. She was really upset and it took me 2 hours to get her back down, plus she woke again an hour later.
My back has been in muscle spasm this week due to lifting her and the buggy, and DH knows this too and knows I need to rest my back this weekend.
I'm still fuming! He's now having his lie in, as we each get one lie in at weekends. I was tempted to switch the light on at 6.30 and start debating whether it's really ever been agreed that we each get a lie in, but I didn't.
How do I handle this today?
