With all due respect I don't think you have much of an understanding of how addiction works. Because when you're on gear the decisions you make aren't rational. You don't think, yeah I'll call in my social capital and get my baby-wearing mates to have the kid while I cook up. Or I've got the money so I'll make sure I get a nanny over before I start nodding.
No. Instead your trapped in this fight in your head where you think I really shouldn't be doing this, but just one more hit, but there's my baby, but no one will know, but my husband trusts me, just a small relief, lift the weight lift the weight. And round & round you go. Until you create a small opportunity, and the desperate anticipation and the disgust, and the thrill, and the guilt dissolve in a spoon.
Addiction is secretive and selfish. The battle between what you know is right and the need to let it all go.
Just saying she could have hired a babysitter misses the point by a fair margin.
