My in-laws are perfect grandparents to our 11month old DS. We always knew that my FIL would find being a grandad hard because he was rarely there when my husband and BiL were babies due to being in the RAF. MiL regularly helps watch the baby and they have him overnight. We’ve asked if they could have him for a few hours on Christmas Eve so we can prep for Christmas (we’re hosting) but MiL is at work, so we’ve asked FIL. He said that he doesn’t want to because he doesn’t feel like he knows how to, he doesn’t know how to change a nappy on his own and doesn’t know about bottles etc. I really understand that he is worried but I really want him to try it. It’ll only be for a couple of hours, DS won’t need a bottle, and likely won’t need a nappy change, he might need a snack which his grandad already knows how to do. WIBU to push this more with him and explain that it would literally be sitting and playing with him, or should I just leave it and DH and I manage on our own?
