I go back to work in under 2 months out of necessity, and DP will become a SAHD. DS is currently 4 months. I have found myself pretty much following attachment parenting principles (at DS's insistence!), with the result (or maybe it would be this way anyway) that DS is very clingy and close to me. He also loves his dad but needs me for bedtimes/naptimes to feed/rock him to sleep. He's funny with anyone else, and is grumpy and whiney when alone with DP.
I'm trying not to worry because he could be totally different in 2 months but DS is a particularly difficult baby, very sensitive, alert, easily overstimulated and really struggles to relax enough for the sleep he really needs to avoid meltdown. I feel that I am the only person at the moment who really understands/reads him well and responds to his needs. Whenever I have left him with DP (at least once a week) he usually ends up having to walk the town with DS in the pram or sling howling.
I'm sure loads of people have been here and survived and I also know I might be worrying about nothing but if anyone has any experiences to share I'd be really grateful, am just having a bit of a wobble
