Normally I'm an eye roller when it comes to advice - which is ignorant because often it could actually be helpful! But my first instinct is to ignore. What advice do you wish you'd taken?

For me I can think of two specific instances:

"The carseat is very heavy, if you're petite I'd reconsider"
(Britax Chaperone is FREAKING HEAVY why didn't I listen! My baby is now 16 lbs at 4 months and I can barely limp along with him in it.)

"Be careful, it's slick"
(I was buying a sled....and it was slick. Broke my back in two places and my tailbone. Hello chronic lifelong injury, not worth it to have snow fun!)
