It’s ok to ask people to wash their hands before touching your baby and not to kiss your baby as it may transfer virus to your baby. However, it’s best not to be too clean and too over protective. Firstly your lo will learn from you. Secondly this will not help with her immune system, whereby when your baby go to school, she may fall sick easily, which I don’t think you want that to happen. Not sure how old is your baby, but you can bathed her 2 times per day - morning and before bedtime, guess it more than enough for baby.
Try to think of it as the younger she’s exposed to germs, the stronger she will be, which is scientifically proven and true.
