We live next door to my parents who are in their late 60s. My OH works from home and I've just gone back to work part-time, so our arrangement is that when he is very busy and needs to work while I'm at work, my parents take care of our DS.
Because of their proximity they've seen DS pretty much every day of his life, so after us, they are the people he knows best, by a long way. But every time my OH leaves him with them, he says he cries almost non-stop. He gets annoyed saying it's because they don't know how to soothe him properly, but I think part of that is just typical complaining about the in-laws.
Is this normal for a baby to cry a LOT when with grandparents, even though he's a calm baby with us, and stops crying as soon as one of us takes him back? Are they doing something wrong, or is it just normal baby behaviour? My OH says he can't get much work done because he can hear his son crying non-stop and has to keep popping over to see what's wrong.
