It takes a village! I’m so grateful for my mum and mother-in-law I would explain to your husband maybe do one day where baby goes to them and then a day out together or something best of both, don’t want to annoy them if your planning on going back to work my family have done childcare until I got funded hours and it’s saved us thousands or I wouldn’t of been able to go back and couldn’t afford to do that xx
I would agree something between you and your partner and then stick to it together. I do think that 3 or 4 full days is a lot as my daughter was in a routine before 6 months and this would have not been the best for it. You could say 1 day for your lo to spend with them. This could also give you some time to yourself then if you go out anywhere with your lo you could always invite them sometimes. I do see your partner's point but I also know how much easier it is with a lo when you have a few of you around. I guess she is his daughter as well so you need to agree on how your daughter should be spending her days ect
If you get on with your in laws then i dont see an issue, if they have her on their own it gives you some time to yourself. If gives you someone to trust your baby with if you had an emergency & needed to drop her off asap. Yes they could come to you 1 day but gives you chance to get out the house too which is needed with a baby. If its his 1st maybe hes just trying to be protective and its all a learning curve for everyone. Noone is necessarily wrong, just trying to do what they think is right x
