Re: My baby just started crying when I lay him down to sleep. Separation anxiety??
Oooh! I completely second a routine before naps/bed. It can be as simple as reading the same book beforehand. Just something to prepare them for the fact that they are getting ready to go to sleep now.
I know this is a tough age, but it really helps if you can firmly stick to bedtime/naps. I think it just confuses them if they sometimes have to nap and sometimes don't have to.
