My DS is 16 weeks and has started taking naps that are 2 hours or longer. My mother says to let her sleep but I am worried she may sleep too much during the day. I can't believe I am even asking about this as DS napped for 45 min max! Anyway, she had been doing really well at night so I wasn't worried about a routine. We followed a eat, activity, sleep pattern though most of the time and she would go for 4-5 hours at night. However, we haven't been able to achieve that lately. I would love to get back to sleeping from 10pm to 5am. Are the naps causing issues? Thanks.
