TLDR: 8 week old son loved daddy more than anyone but now won't settle for him. Concerned about rebuilding/maintaining attachment.
Since my DS was born 8 weeks ago, my DH has pretty much been his favourite person. Over the last few days, however, he just won't settle with him and constantly screams during the evenings. DS has always been an evening cluster feeder but I used to be able to get a shower and put my pyjamas on but things seem to be going in the wrong direction.
My DH is very upset about this and is worried now he's back at work, DS will continue to lose his bond and attachment with him.
I feel like it's probably just a phase but that's easy to say when you're not on the receiving end of it.
DH works locally so spends his hour break at home and usually holds DS/plays with him/takes over care needs while I get dressed and do a few jobs. He finishes work mid afternoon and so again he takes over for a time and then we spend the evening with my parents too when they get home from work (multi generation living) as a family. At this point, DH is reluctant to take DS or be left alone with him because the screaming isn't pleasant for either of them.
DS is EBF and DH works strange shifts so we all go up to bed around 9pm, DH reads a story while I feed DS, then DH sleeps in the spare room and I take over for the night shift.
Other than introducing a bottle of expressed milk in the evenings, are there any other positive steps we can take to stop this getting worse? DH is taking shared parental leave starting when DS is 5 months old, so he's worrying about that already too! I hate seeing both DH and DS so upset but I don't want to keep taking over to settle him as I feel that won't help.
