I wish people wouldn't pick and choose what to care about when it comes to parenting. I know a girl who is against vaccinations and her child eats a vegan diet. She makes it known that she judges people who vax and eat dairy and meat.... Yada yada. No judgement here, to each their own. But I messaged her regarding her daughter's seat and she didn't seem to care.... She said that it was loose because she normally has a thick coat on, then I mentioned that she shouldn't wear a thick coat... Politely of course. Then she starts complaining about the car seat and that was it... Hope she takes what I said into consideration. I would hate to see her child harmed, because of something that could of been avoided you know?
