I don't know your situation, but I don't think in general it's any more expensive. My friends all say "you have to buy them a cell phone and pay for travel baseball and competitive gymnastics and buy them brand new clothes, I just can't afford a kid."
Not saying you're saying that, but typically when people say kids are too expensive, they mean keeping up with the Joneses while raising a kid is too expensive. Goodwill clothes and rec league soccer and not buying them a cell phone is a perfectly acceptable way to parent, the only things that have gotten more expensive are society's expectations of how much parents should buy their kids.
