This is a parenting tip that I just barely learned with baby #5. it’s so advanced and so counterintuitive that only the most advanced parents may employ it*:
If your child starts to throw up, DO NOT pick the child up and dash madly for the closest bathroom. You will only leave a giant trail of barf behind you. Instead just stand there with your vomiting child, feeling helpless and grossed out (and mortified if you’re in public). But all the throw up will be in one little spot, not all over the western hemisphere.
*Ironically I learned this from a woman who only has one child. So I guess I shouldn’t act like such a know-it-all.
