Hi.my baby is 27 days old and he got sweat rashes/pimples on his neck and face and it looks like red bumps and somewhat pus on red bumps.what to do for reducing these pimples

A. U. First can you check with your paediatrician ones because without proper check up I would not be able to assist you with anything because first you have to know what is the reason behind it and your child is just a newborn child with very much important that you pay attention to it and take a proper medical consultation for that
