question: Hi, my son is 18 mos. old and won t sleep. He has been very irritated as well. He just screams bloody murder when we try to put him down & when he does fall asleep, he wakes back up also upset screaming within an hour or so. We get him up and he acts better but obviously still easily irritable (probobly cuz not enough sleep obviously and also grabbing at mouth teething)... but what else is it? This is not like him. We just give him medicine in his bottle at night when he s like this and then stuff on his gums... but he is NOT interested in sleep..? Pls help! No insurance either yet... ;(
