You can't bond with your baby if the entire time you're breastfeeding you are glued to your phone screen completely ignoring the baby!
Bonding while feeding (breast or bottle) comes from stroking the baby's head or hair, looking in their eyes lovingly, talking to them,singing lullabies etc. She didn't do ANY of that. She simply put the kid on the boob to burn calories and all but forgot they were there.
I personally think she secretly loves the fact Andrea wants nothing to do with her because that means less work for her. He probably only wants J or the nanny if she there to do everything for him. Her pretending to complain about it is just to deflect from her true feelings of loving not having an annoying kid being dependent on her.
