Talia head control

At two and a half- three months of age, I started to worry as Talia´s head was really floppy. Cognitively she seemed all there but her muscles and body just seemed so week. She seemed like a rag doll. Car trips were really scary as her head would bob up and down. My husband and I would drive - one of us constantly trying to hold her head up and also watching out to make sure she didn't vomit. Cognitively she seemed ot be developing although 3 months is still early to tell. Thankfully I spotted Talia falling behind immediately as I have 2 other kids and clearly remembered them at that age. My paediatrician was great and monitored us on a weekly basis but she stayed around 3 kilos for ages - now at 7 months she is only 4.45 - so you can see how slow everything is. At about 3 months we had a scan of her head done through the fontanelle and thankfully it was clear. We decided to give her till four months as really she could have just been a slow developer and given problems in the womb - perhaps she would catch up. By four months her head control was starting to improve and cognitively she was all there - she could follow us around the room and chuckle. She was the most loving and warm baby. My two other girls were fantastic with her, constantly stimulating and cuddling her.
