Is this enough?

I’m a single mom of 3. Ages 5, 3 and 1. My first 2 kids, their dad hasn’t been in their life going on 3 years so it’s been a absolute struggle for me doing it on my own with no help. Well thanks to my youngest baby’s dad he keeps all 3 kids for me so I can work, I started a month ago & this is my first time saving. Do you think $50 out of each check is good to start off saving? So far I have $100 in my savings account & I only make $2400 a month. I need tips please.
