my baby 8 months old she weight 6.9 kg it is normal or low weight

A. It’s a really low weight at this age a child should be more than 7 1/2 to 8 kg basically by the time of seven months old child should be about 7 1/2 kg so this is a little less as compared to that which is why I think it would be good that you try to give a diet to increase the weight of your child
