Your son is too cute! I love that pic. Anyway, we had that problem around the same time.He would only take 1 nap a day and it was miserable! Don't know if its part of the growth spurt but he's napping just fine now. GL
We just had 48hrs of practically NO sleep! It was miserable. And then, last night, he just decided to sleep again and is back on a more normal routine.
Re: 5+ weeks- learn to not nap?
