I think my baby is going through a 3 month regression. My question is about naps: what kind of environment do you create for naps? And how do you let them fall asleep on their own? She used to be able to sleep anywhere but now getting a little more trickier. Do I sooth, rock her? Some say that just stimulates her at this age. Do I let her cry to nap? How long do I let her cry before checking on her? I read that we're not ready to sleep train until her nap schedule is in place.

Should I be putting her in the same sleep sack as I do at night? I have no idea how to get her to nap anymore... She's changed so much!
