That's exactly why we made the decision for me to stay home, I did the math and it would be more expensive than rent to put baby in daycare. Like I would be working just so the baby could go to daycare.
I pay $420 a month working there and she is only 3 days. If I took her there 5 full days without working there I would pay $1080 a month!! That is nuts and it is another mortgage payment!
That was the deciding factor on me staying home with our daughter. I'd be working full time and only bringing in an extra $100 per month. Not worth it!
