A friend came to visit me and asked if she can take the baby. Baby is 16 weeks old, I gave her the baby and she did a quick peck on my baby's cheek. I was shocked that why would she kiss other people's baby. I was upset and when she left I wiped my baby's face but I am feeling quite upset about her inconsiderate behaviour putting my baby's health risk. Baby has been fussy last night and I am feeling quite worried about my baby's health. Baby has all her vaccines so far.
What should I do and what should I say to her and other visitors coming to our place to see baby?
