Ex wants me to pay for kids’ school uniform

[dancingdad]

We are separated and have twins who are starting school this September. I pay her child care each month (£400). She’s sent me a long list of uniform they need for school. Am I right in thinking the child support I pay should go on this?
she has a kid by someone else too and the father was never asked to pay child support so I’m thinking my money will no doubt go on his uniform too!

sorry but £400 a month is a pittance for one child let alone two.as a father you should be doing your upmost to support your ex and your children even if not together you should at least offer to pay half of the uniform costs
