My LO is 9 weeks. She just started sleeping from 9:30 to about 6:30. I have had her on a 3.5 EASY with a first feeding at 7:00. My question is her sleep cues come at about an hour and she goes down pretty quickly. This means she usually wakes up about 45 minutes before her next feeding. She is not hungry or grouchy when she wakes and is fine waiting to eat, but then A time after eating before the next nap time is only about 30 min. Is this OK or will it turn into a problem ?? For example- Sometimes she wakes at 6:20 and I don't feed her until 7, she starts yawing at about 7:30 I don't want to feed her any earlier because of my schedule....thank you
