Going on 11 weeks here soon of still having an every 3 hour waking window especially at nighttime😩 It seems more often my LO wakes herself up right after she spits up a ton. Keeping her upright,burping, angling all the tricks still do not help because no matter what this girl still spits up even 2 hours after a feeding. Is there anything I’m missing to try with her?! The lack of sleep is really getting to me and my husband especially as both working parents.
