I'm a single mother to an almost 1 year old. It's just me and her no pets we might get one eventually but currently none now.
She will probably be asleep when the sitter arrives or she might be up. She sleeps alone I turn out all the lights and put on White noise for her and give her a bottle of milk and then she's pretty much set for the night. If she wakes up at all I make her another bottle and give it to her and she usually falls back asleep you might have to change her at least once if she has two bottles if she only has one she usually makes it till the morning.
I work night shift and it's not a set schedule so somedays I won't need anyone. But my schedule changes sometimes, I will obviously give a heads up. Or I may have something going on in the daytime and will ask a weak advance if you're able to watch her in the daytime.
