I've had 2 boys coming for half days once a week this month (a break for their mom as their Dad is working away). The older boy, 4.5yo, has been begging to stay the whole day. Their mom asked me to do full day this week, and I agreed without thinking. The younger boy (2.5yo) still naps, around 1, same time as our quiet time. Right now I put my baby (8mo) in her crib in my room, dcb1 (1.5yo) on a floor bed in my daughter's room, and my daughter (3yo) and dcb2 (4.5yo) stay in the playroom for quiet activities like colouring or playdoh.

Dcb1 cries at nap time, I'm worried the new little boy won't be able to sleep. Should I try putting them upstairs in the same room (I can set up a second bed). Or should I move my baby to a play pen (travel size, not big enough for the 2.5yo), put the new boy in her crib (he sleeps in a crib at home)? Or try to get everyone to lie down?

For those with mixed age groups, what does your quiet time look like?
