Any mamas have any tips for getting through the 4 month sleep regression?? My little man won’t take a pacifier anymore as he prefers his thumb. And I don’t want to do CIO but sometimes letting him cry for a little is the only way he finds his thumb and soothes himself back to sleep. He’s waking up around every hour to hour and a half, and prior to this he was sleeping 9-10 hours at night consistently. Also trying to avoid forming bad sleep habits during this time. Help please!!😊
