Day naps

Krista

My son is 11 weeks old and during the day, he takes short 30 mins naps in his crib like clockwork. If I let him sleep on me or next to me, he sleeps for like 2 hours. I thought maybe it was my smell so I slept with a security blanket and put it close to his crib but that didn't work. I realize he is still young I'm just wondering if anyone has any tips on working towards extending the 30 mins. Thanks!
