my baby girl is 9 months old. her breast size is apparently larger than usual. is it normal? what should I do to make it normal?

A. Okay a lot of parents do not know this but when the child is born they have some milk into their breast region whether it is a boy or a girl there are two opinions about it in some cases they say that you should press it and take it out which is completely fine and sometimes when you press a little bit of milk can stay and it looks like what it is looking for your child but I am not very sure that this is the same reason or there is anything else better to check with your doctor once
