E is 4.5 months old and has been waking every 3 hours or so to eat, at least I assume she is hungry so I feed her, which may be my own mistake. She was going 5-8 hour stretches so I'm wondering if it's a combination of teething and sleep regression. How often was your LO waking at this age? Should I be offering the pacifier vs feeding her every time? I'm wondering if she is now just waking out of habit vs hunger. Any tips for me?
