Please suggest some tablets for increase breastmilk My baby is sucking thumb too much he is now 4 month 13 days old After feeding liquid form in potty

A. hi all things are normal please dont take tension first thing , as child is sucking his thumb its not necessary that he is sucking the thumb only because of hunger it could be part of exploration to their body too although ,if you are having signs like child remains hungry after feeding , your breasts stays loose and soft then to improve your breastmilk supply ,you can start taking suppliments like laptadine tablets
