Am i just being paranoid?😬

So I'm a very OCD person when it comes to personal hygiene and keeping things clean and tidy.

We currently have a 2 week old baby. I have always told people that they need to wash their hands, do not kiss my baby and make sure that they are clean.

However, people do not do this.. or they don't do it properly. I.e they do not wash their hands with soap. Just water them for a few seconds.

I have already told people to do it properly etc etc but it just doesn't seem to go in their heads.

I am really worried about our little boy becoming ill. But im also not sure what illness he can get from people not being hygenic...

Any advice? And what should I look out for with people not keeping up with their hygiene.

I'm not wanting to prevent these people from seeing our little one but no matter how many times I express my concerns no one listens or does anything about it.

I always look out for if they go to kiss my baby on the lips and so far that's not the case just the forehead or cheek. But am I just being overly paranoid?
