Silvia transfers between mother and baby is healthy and normal and good.
The babies gut bacteria aren't formed yet at birth, it comes from the mother. Traditionally babies get it from mothers prechewing food and giving it to their baby.
There is a lot of evidence that a poorly formed or 'wiped' gut bacteria biome in babies and child causes autism like effects. This can happen from anti-biotics as an example.
Kissing between couples is though to have evolutionary originated from mothers kissing/feeding babies prechewed food. Much like how animals move to get patted because their mother licks them as young/newborn and patting taps into that.

What this mother is going is the most normal fucking thing in existence. KYS
