he just cries and kicks out when I try putting him to sleep, it takes 1.5 hours. He’s squealing and crying and throwing his head back. My back is gone, I’m crying. Why won’t he just sleep easily? I watch carefully for wake windows, sleepy signs like rubbing eyes and yawning. Nothing makes a difference. He just struggles to fall asleep without me holding him and rocking him for ages. ADVICE? Because it’s ruining my life, health, relationship, mental health
