2nd nap

Kacie
I really can't complain because my baby is an awesome sleeper but we struggle with his second nap. He takes a really good morning nap but his afternoon nap is only 30mins maybe an hour at most. Because of this we have to put him to bed for the night at 5 or 5:30. I'd really like him to go to bed closer to 7. Any advice on how I can get him to take a better afternoon nap?
