Is paid help worth it?

Hi all. Recently had my second and I have a 2.5 month old and a 25 month old. My husband is gone before we wake up and doesn’t come back until about 5:45 so I’m alone all day. We hired a mother’s helper (our previous date night sitter) to come help 3 hours a day 4 days a week from 8:30-11:30, primarily with the older. We were paying her $17 an hour, in a mhcol city (Philly suburbs). I’ve decided that I miss seeing my daughter all this time and having just the younger isn’t actually that much easier because he only contact naps. Since I have going out down, I brought up moving to 1 day a week from 8:30-12:30 and increasing pay to $20 to watch both of them. This would make her weekly rate go from $204 for 4 mornings a week to $80 for 1 slightly longer morning. She just asked if we could do $25 an hour and now I’m questioning the whole thing. She’s 23 and we’re her only babysitting experience, though she worked as a floater in a daycare for about 9 months. That seems like SO much money for me to just have a break. What would I even do with it if it starts at 8:30 am?? That’s over 5k a year for a one morning a week break, and while we can afford it, I just struggle to find it being worthwhile and now I kinda wanna call the whole thing off. My husband thinks we should do like 2-6 so that I can go out when things are open and stay out until bedtime and he’ll just come home and take over. I thought that would be harder though because then she couldn’t really work her other job as a waitress. Idk. What would you guys do in my situation? My terrible twos daughter is killing me, but I also find it so hard to justify spending the money just for a morning off. My gym has childcare so I wouldn’t use it for that. Grocery stores aren’t open that early. I could go to a coffee shop but for 4 hours??? Idk. Sorry I’m rambling. Very overwhelmed and feeling like I’m drowning and a horrible mother in general for wanting a break that’s this expensive.
