Hey the weight growth depends upon the birth weight, so if the child has doubled the birth weight in first six months, need not worry. We moms of twins often mistake by comparing the weight of two kids. Compare the weight of the child with her previous weight only and see if that's as per the milestone. Also if the child is active, you have absolutely nothing to worry about.

thanks to everyone for urs helpful answers:)

The birth weight should double by 6th month. <br> Baby should be active. <br> If your baby is active and has gained weight with respect to her birth weight u need not worry. <br> Genes play an important role, it may be because of their gene that they look slim. It is a myth that since they are twins one will be weak. I have twins in my family and almost all sets were full term, healthy babies with the same weight ( except mine, they were pre term)<br> It is always good to have active babies who may be lean rather than sluggish obese baby who can end up having health issues later.<br> Feed them right, healthy food and dont worry.

In twins most of the time it happens that the one get more n other less wt. So it's normal

So cute.<br> They will gain weight.<br> It's ok in twins sometimes one baby looks weak.<br> But it's ok if they are <u>active</u>
