How to get her to Nap longer??

[Jackieluv]

So my baby is almost 4 months old and sleeps for the most part, throught the night (I get her up one time to feed her). 730pm-630pm. I am getting her in the habit of sleeping in her crib whether it be naps or night sleep....but her naps are only lasting 45 minutes (3xs a day) is this sufficient or should it be longer right now? and if it should be longer, any suggestions to get her to sleep longer than she is??

Naps can be kinda rough from 4-6 mos old. My DD would do well for a few weeks & then not well for a few weeks. The only thing I can think of to get her to sleep longer is to swaddle her & have white noise. Is she really tired for her naps or could she maybe go to 2 naps??? Good luck!
