Mommies my 4 week old DD has been having awake periods of 3 hours for the past 5 days or so. She'll stay awake at different times a day for 3 hours and then sometimes sleeps for 4hrs, 2hrs or 20mins. I really don't like that she's awake for this long. By the time she settles she's ready to feed again. She doesn't fuss to much during these awake periods but tends to feed quite a bit(BF and supplementing and she's 40mins breast and then takes 4-6oz formula) during this time. She has a growth spurt last week so I don't think this is a spurt again. Any suggestions on how to get her down before the 3 hr mark? We try swaddle, bath, etc nothing seems to work.
