Sounds like possibly a sleep regression to me. But also, 3 hours is a fairly long nap. I wonder if he’s waking because she isn’t tired enough for bedtime. Just a thought…
Yep! Same here. My son is a great sleeper but for the past few weeks he’s been up 2-3 times a night crying. We’re trying to stick with a routine and I’m trying lavender oil 🙏🏼
Try Magnesium lotion. It helps my kids get restful sleep.
