New Babies night time feedings!!

Carolina • 1 fresh successful cycle 2015 ! 15 month daughter via IVF and going thru FET Aug 2017 🙏🏼🙏🏼 1 embryo ready for transfer!
Hey mamas! Have you guys kept waking babies up for feedings at night or do you let them sleep? First 2 weeks i was told to wake her and feed her every 3 hrs. I went to peditrician at her 2 week appt and was told i can now let her sleep thru and just feed her when she wakes up at night. However, seems like she is on a schedule now ans wakes up on her own at the 3 hr mark! 🙈🙈🙈 Really? last week she would play hard to get when it was time for her 3 hr feeding. Just womdering what ur drs are recomending for these littles. 😊😊😊😊
