My 5.5 months baby’s trunk is not stiff when held upright or when made to sit with support. He bends towards his right when held upright. When will his trunk gets stiffer? Is the delay because of his weight. He weighs 9 kgs.

A. It is normal for your baby's head to wobble, at this age. Making sure that his neck does not wobble too much, it is important to give it support. If a 6 month old baby's head is still wobbly do consult a pediatrician immediately!
