Sleeping.

Melissa • Married to the love of my life! Had my sweet Madison on 07/31/15 and now due with baby #2 Oct' 16.
How many 12 weeks olds are sleeping through the night already? My daughter wakes up once to eat 5 oz of formula, and I'm just wondering when she'll sleep all night. She has 5 oz at 10p.m then wakes at 2-3 then 7.
