A.S.
Try to keep him up a little longer in the morning, with fun games and toys, until eventually he is only takeing one nap...that may make his nap longer, and more productive. As for nursing him to sleep, I did that with my son, and he is a well rested...long sleeping 13 year old boy now! :) However, my now 18 year old daughter NEVER took naps longer than 15min. at a time...until she was about a year old, then it was one long nap, about 1 1/2 hours. He might just be growing into a person who is grumpy when they first wake up...my daughter is STILL that way...she's not a "morning person" lol!
