Weekend nanny? Yes or no?

I'm not super rich but I've been seriously thinking about getting a weekend nanny for this new baby.

I've got one child already and my mom helps tremendously and she goes to my moms on the weekends so but I don't want to over load my mom with my responsibilities and give her 2 kids!

For the sake of my sanity( after the baby is old enough) I would love to hire a night nanny on the weekends just so the pace of my life could feel the same as it does with one child. who could help out with a little cleaning and keep an eye on the baby.

I figured it would only set me back about 150$ a week for a few hours out on the weekends and it would help me keep up on house work.

Is that selfish? If you could do it would you? Or will you be doing it?

Add*

I would not go out EVERY weekend. But I would still have the nanny every weekend for help even if it's just so I can watch a movie in my room and have her do some house work.

I am a single parent,

my mother has my other child on the weekend because, I had the baby when I was very young. So for years I lived in her house so moving out was not routine for my child. My mother and siblings go camping or often do outdoor activities every weekend (things I wouldn't do in a million years) so my child gets to have fun with her grandma and I get to have time to myself, weather I go out or stay home.

It's not about being a parent "part-time" if you don't have a second parent in the home help is nice. My daughter doesn't have a second parent period.

I dont camp with my child because I don't camp I don't do out door activities, if I'm camping it's because there is a trailer. also I don't work all week I actually work weekends and only 2-3 weekdays I spend a substantial amount of time with my child during the week when I work she isn't even awake. I don't know where people are getting the assumption I don't spend time with my child because I hate camping? Or where people are thinking I'm gone all week??
