Baby only stays with me and doesnt go to anyone else. How to improve this?

A. Actually kids recognise their mother by the smell which is why the more clinging onto the mother only and they had been with you for a last nine months also so that is why this may be happening and your child is used to hearing a mother only which is why this is happening so if you stay away for a while the child would cry but the other person would take and comfort the child will stop crying that’s a normal thing to be seen
