Thanks playfelt, good point too. I know what you mean and I myself would not be sure how I woudl feel about the situation if the tables were turned. He has one rule for me: he doesnt do diapers except for our son LOL. The parents meet him whenever we have interviews and they have clearly expressed to me that this arrangement is 100% fine. I asked them how they would feel if my husband did the "morning shift" when the baby is here. He would get them in the morning, take them on morning walk and tak care of snack. I would get to sleep in as much as possible after being up every 3 hrs in the night etc. They love the plan and are, truly okay with my husband. When he is not here, the kids ask for (my son's name)'s daddy. He is home everyday at 2pm so the parents see him all the time at pick up.
Anyways, I thank you for the concern and you can never assume if parents are okay with men, as you pointed out.
