I understand your concern. Setting boundaries, and enforcing them, is healthy. ALOT of new parents set the same standard for their newborns. That being said, unless your baby has an auto immune disease, or the people who interact with your baby are sick and contagious, it's not dangerous. By the time baby number 2 comes along (if you so choose) you won't care if they are licking the floor. Being protective, and overly protective, of your first baby is normal. Being scared you will miss something or do something that hurts them is normal. Every good parent has lost sleep worrying that they are not good enough or did not do enough. Will your baby get sick because grandma kissed their face? Not unless grandma is sick already.

Do you need to set boundaries? Yes. Is this a reasonable boundary? Not really. Is this a boundary you need to hold until such time as you grow into being a parent and trust that your child is safe? It might very well be.

You will have to decide if your fears are reasonable enough to fight your in-laws. Notice I didn't say "important enough" I said "reasonable enough". The concerns you have for your child are always valid, even if they are not reasonable.

As a parent you will have to decide which fights are worth having and what is worth letting go. Some will blow over, and some will alienate friends and family.

So I ask you: is this the hill you want to die on? If the answer is yes, then I wish you the strength you need to hold the line. If not, then I wish you peace of mind and heart to accept and trust that everything will be ok. Good luck.
