I gave birth to a baby nearly 4 weeks ago and me and her father split up while I was pregnant. He has agreed to pay his way for her and he sees our baby at least 2 days a week. I was just wondering, what percentage of his wages should be going towards the baby?Having a baby is very expensive and I can't do it all alone but wanted to check that he isn't going to stitch me up with hardly paying anything towards her. Please help.
