Ever had a baby with colic? They don’t sleep as much, they cry instead. A mom can spend hours just rocking, bouncing, carrying, putting on a vacuum, on the washer, vibrating chair, trying different music and positions -ANYTHING to get some quiet and ease the baby. It takes a couple weeks after the baby is born to set in, true, but after ten days your kid can scream for 4 months straight, night and day. Ask me how I know.
It’s physically and emotionally difficult for even the healthiest, most devoted parents. If Ari has colic they just won’t manage at all. I think they will miss critical bonding time under the best circumstances but I can see Alex leaving a screaming baby to get to the club.
