I will have a 4 year age gap between kiddos and was last pregnant/paying attention to baby stuff in 2014. I was just wondering what new stuff has come out that is awesome or more readily available or makes life easier. I see people reference the Hakaa pumps, which I swear were not common four years ago, and that makes me wonder what other new stuff there is. If you had a 2014 baby and then a baby more recently, did you discover anything new that you wish you'd had the first time around?
