catnaps all day...

Meg
Should I do something about the fact that my 4 1/2 month old only takes 30-40 minute naps during the day? At night he averages 11 hours straight. He's a really happy little guy and seems to be growing just fine. The most sleep he gets in 24 hours is 14 and some days he gets down to just 12 1/2. Would love to hear your thoughts.
