hi , still the baby is not showing interest in tummy time.if i do he is crying and turning front. he is rolling over the room and all places .backside like flat head like hair fallen.. sitting with support of pillow, sofa , my leg inside and lap. I'm very depressed about this. eating ,sleeping, very active ,doing claps. He likes self weaning.. milestone delay or he is going to skip crawling i dont know but I'm afraid..
