Thank you so much for the trade ! <| sep |> You can ' t enforce that though . It ' s one thing to incentivize one child but you can ' t just ban reproduction . <| sep |> that is brilliant ! <| sep |> We have 4 year old twins , so my memory is most likely missing some aspects it ' s amazing how twins can wipe out your memory , you ' re too busy to reflect and make new ones ! . In our experience , the baby years were almost free from a budget standpoint . We work opposite shifts , and I nursed them , so the two biggest expenses were eliminated . We also graciously received lots of handmedown clothes , and new outfits from the grand parents . We got diapers from Amazon Mom subscription , so I ' d say that was the biggest expense at roughly $ 75 a month if I ' m remembering correctly . We made baby food from scratch from vegetables , so that wasn ' t much , and otherwise they don ' t eat much yet ! We are big on budgeting too I ' m sure you visit rpersonalfinance ? , and found clever ways to save . I think that for twins the real expense begins where we are now , with two soccerballet classes , two preschool payments , etc . , but we have been able to get a discount for school by having a nice relationship with them . Feel free to ask me more questions , as a fellow thrifty twin parent ! It ' s a great ride , best of luck .
