At first my bub was sleeping 2-3hrs twice a day n going from 10-9am (with dreamfeed n 1 or 2 wake ups)
Babies sleep a lot! Is she alert while awake? I generally follow:
Wake up, feed, play (awake time) for 2 hrs, sleep and do it again. So bejng awake for 2hrs n sleeping for 45mins is fine!

Dont stress.
