Here is some info on the babies in the Baby AU Comic (which I am still drawing on the side)
Tony Stark: Trouble maker, likes to slams and breaks things, giggles and laughs a lot, LOVES Stephen Strange, and tantrums when he doesn’t get his way.
Stephen Strange: A chubby sweetheart, cries a lot, LOVES Tony and loves to cuddle in Christine Palmer’s arms.
Loki: Also a sweetheart, very curious, only baby who knows how to walk, likes Tony but not Stephen. (Its mutual)
Thor: Loving and caring big brother to Loki and helps out adults with baby care.
If you have any suggestions or ideas, let me know.
