I think herself and Julie should move in with each other, then they wouldn't be doing it all "on their own" anymore, and couldn't complain day in & day out about how hard it is being a "single mom"
She has a very basic job, which is highly flexible at the moment, that she can do from home. One child, and he's too young to even need home schooling. He's plonked in front of the tv/iPad for the majority of his waking day.
If she really wants to give him time, she can hold off on her admin until he goes to bed at 7pm. Working 7pm - 12am every night would give her 5 whole hours. I'm sure entering people's weights into the system can't take that long. If she held off her social media until he was in bed too, she would have even more time.
It's like she's only just waking up to adult life right now. Before, the creche did all her child care for her, this is her first taste of real life & she doesn't like it, does she?
