my baby have very irritating nature she always do mamma Mamma n dont mix up with anyone... Wat should I do

This will gradually disappear. Take ur kid outdoor like a park once ur kid starts enjoying outdoor activities she will start to mingle with other kids n stop worrying you

It is normal for a child to feel flustered and want to be with the mother especially in large groups. Do not push the baby away in fact cuddle and reassure. It will help your child gain more confidence once he is assured of your love.
