My baby is 2 months old today, (8 weeks and 5 days to be exact) last night she slept 7 hours straight. Which is the longest she has ever slept. I think it might be due to the fact that I mixed some formula into her breast milk earlier in the evening and she also had a bottle of formula only in the evening. but her last meal before she slept was 100% breast milk. I felt kinda strange when I woke up this morning and realized she pretty much slept through the night and never cried. I decided to wake her up around 6am to feed her. I just wondered if this is normal for a 2month old who is primarily breast fed?. Should I have woken her up earlier, or just let her sleep as long as she wants
