My husband and I were talking about our kids and jokingly I said I would love one more (we have two right now). He said if we had more money he would love to as well, I said well chances are we have another boy (my luck haha) and we will save costs already having a range of sizes for seasons, plus most, of not all, big ticket items. So just for fun discussion purposes, because our youngest is only 5 months old, how much more expensive was it to have a third? I am becoming a stay at home mom, so child care is not an expense we will have moving forward. We also already have a third row vehicle (dodge durango). We would need a new car seat since the infant one will be expired by the time we would theoretically be ready. Where did you see your expenses increase?
