i was born extremely premature and wasn't held for a few months because of being too sick and then my mom having medical issues of her own.

i am surprised they do not have kangaroo care where your granddaughter is. if your granddaughter is stable enough, it is proven to actually help them regulate their breathing and be calmer. they use it a lot with preemies and sick babies at many hospitals because of how it helps and also during certain medical procedures that might cause distress for the baby. it also helps them to have that contact with their parents to get to know them, etc. but even just touching them in general is good and talking to them. they can put something in with her with their scent too.

i don't feel those first few months of that lack of bonding with my mother was that big of an issue (not that i'd know though) because i needed that time to just grow and heal, etc. i believe more of the bonding is done in the first few months once home and the effect of the environment around them, etc. and they really get to know their parents and the roles everyone plays, etc.

in my case, i do believe my early life trauma was the precursor to some of my issues, but it was the rest of the traumas in childhood and people in general doing things that really caused the longer lasting and deeper issues.
