Good night! Can you please tell me what to do? Maybe the regime is wrong, or it's regression... We'll be four months in a couple of days, but nighttime sleep is awful, it takes so much effort to put him down... for three months it was all so great, he slept very well Now he starts being capricious, wriggling around when I try to put him down, he rubs his eyes and immediately cries Because of this we sometimes go out and ride in the car in the yard, he falls asleep instantly A kilometer of drool ? He pulls all the toys into his mouth If he can't shove it in his mouth, then tantrums start ?
