Rephrased question...?

i asked how do you feel about kissing your baby's lips? im not talking ually of course, i meant when it comes to germs, sometimes if the baby is really little, is it ok to still kisse them in the mouth? my friend does it and it makes me wonder if its ok for the simple fact of her coming from work from a hospital and kissing her 3 month old and toddler... i didn think i had to give a whole explanation but here it is (thi is only for the dirty minded that thought about it being ual) also im not questioning her
