My son started finally sleeping through the night last month. Three weeks straight he slept through. But the past 2 weeks he’s been up every single night and will not stop crying unless I pick him up and rock him for 5 mins. I lay him back down semi awake but he’s up within 10 mins and after doing this several times I end up bringing him in my bed. His molars are poking through, is this why?! What are some things to try? I switched him to one nap and that’s when he started sleeping through. He goes to bed at 7 is this too early? Give me your best tips please!!
