You know.. I was sitting here thinking about his nap..
Since he's transitioning from two naps to one, does he cry out at the 90 min. mark of his day sleep?
I went through this with Matthew, when we went to 1 nap, and he would cry out at 90 mins. I would either hold back and give him a chance to resettle, or I would just stroke his head (always calmed him) and he would reenter sleep. It didn't last long.. I would say about 2 weeks for the whole transition. Sometimes he would cry out briefly, but it would be a second or two, after the transition was completed.
Temporarily, can Bobby take his nap in your room, until Liam has become accustomed to the one nap? You may have to set limits if he's a little rowdy in your room, but it's only temporary..
Sorry if I'm not much help with this one :oops:
