I have a 3 month old that gets fussy after about 40-45 minutes of awake time including a 10 minute bf session. My son was able to go almost 2 hours at this age. She has been extremely hard to get down for naps (cries hysterically after being swaddled). I'm new to this and haven't started investigating much. How long is a typical "wake" time for this age? Should I start trying to get her down after a mere 30-35 minutes? Right now, I've been putting her down at the hour mark. She is a very alert baby and has trouble tuning things out. We have to cover her eyes to get her to sleep. At night, she goes down wide awake at 6:30. Any suggestions?
