Our son has always been rocked, it's taken us typically 15 minutes of rocking and then we would lay him in his crib and he would sleep for naps (2 a day) about an hour and a half and the. For bed at 630 he would sleep through the night until 630am, if he did wake in the night my husband would feed him and he immediately would go right back to sleep! Now he suddenly will fall asleep whilst rocking but the second we lay him in his crib he's up on his feet SCREAMING and crying until someone comes in for him, this will go on for hours both for naps and bed time/ this is about the third day/night of him being this way... he doesn't have an ear infection and isn't ill.... I thought possibly teeth so we've been giving him
