Dropping the Third Nap?

Bedtimes battles have been getting us down!  Nap dramas continues and is apparently our lot in life, but bed time hadn't been a big deal.  Well, the little boy decided that he would show us what he's made of and started screaming and yelling for a lllllllloooooonnnnnnnggggggg time every night.  My parents were visiting this weekend and together the four of us tried something new yesterday.  He didn't nap very well, but we decided - no third catnap for Thomas. Well, he went to sleep like a dream. Today we kept him up a little longer between his AM and PM nap and then no third nap.  Again, went to sleep easily.  I hope this keeps up.  He's a little crispy by dinner time, but can be distracted and amused and will probably get used to it in a few weeks. In other news, we took Thomas to the zoo for the first time today.  He'd rather watch the people walking by than the animals, but we got a family membership and will be returning soon.
