putting our 15 month old to sleep after the night. we have a 4 yr old who i won't have a problem with at all but i'm afraid he will want to be up b/c we will be up, etc. AHHH! i wasn't nervous until today and this has been planned for a year! i don't know if he will sleep in the pack and play there, or crib if he can see us walking around, shutting drawers, going to the bathroom,e tc. (and pls no one tell me that i shouldn't be bringing a 15 month old in the first place...). any advice or tips to put me at ease would be very welcomed. we only have one room...can't afford to have 2 or a suite of some kind. thanks so much!
