Small babies

I am 35 weeks and my babies are small.

Baby A is 4.4lbs which is ok I guess but baby B is only 4lbs which is quite small.

I am getting really worried... how long will they stay in NICU?

Will I be able to keep them with me for a while after birth or not?

36 weeks update

My OBGYN told me that they will go to NICU bc one of my girls will be too small even if I reach 38 weeks and bc she is growing slowly.

Now I am reading on the internet that small babies can have growth and intellectual problems later in life... have you been informed about it? What have you been told?

I feel I have not been prepared at all for what is coming...
