Night owl

Poppy had a coupe times as a little baby when she would sleep for 4-5 hours at a time during the night, and then wake every 2 hours after that. Then she went to taking every 2-3 hours all night long. Now she's waking up ALL.THE.TIME. Lauren's exhausted. Last night she let Poppy sleep on her tummy for a while. It seemed to help Poppy (she slept for an hour straight) but it made Lauren very nervous, especially since Poppy hasn't ever rolled over yet. Hoping for better sleep once she really gets started on solids.
