I need honest opinions!!!

Hi everyone, I need people’s honest opinion. So I work part time as a baby sitter for a little boy(2nd grade) so I can bring my little one (6months) with me. 2-6:30 almost every week day. The thing is I’m barely making my payments and bills. So another family has reached out to me and is working around my other family’s schedule. I’d be working for 2 family’s. Go to family ones house from 10-2 then to family 2 twos house from 2-6:30 then back to family ones house until 8:30. I’ve talked to my partner and he said to do whatever I want and that that will be less time he will be spending with our daughter since I’ll be taking her with me. He said that I should get a full 40hour a week job, and that I’m almost 24 and that it’s not what I should be doing. But he doesn’t work, or help out with any of the bills. I sort of feel like it may be too much hours on me but I’m not really sure what to do. I need the extra money. What’s everyone’s honest opinion?
