Hi
DS is 6 months old and has recently moved from 4 to 3 naps a day. However, only the first nap is a decent length (1-2 hours) and the other two are really short (30 mins). Although a catnap seems fine for the final nap, I suspect the lunchtime one needs to be longer. Any ideas how to extend it? I've tried putting his dummy back in but by then he has seen me and given me a big grin, and he's wide awake! 
I worry that on the days when the first nap is only an hour, he ends up with just 2 hours of sleep for the whole day, and is quite cranky by bedtime. We also have to make bedtime very early to account for the short naps.
Thanks in advance!
