I am going to complain a little here. Surprise, surprise. Why do people constantly feel the need to comment on your parenting skills? Of course I knew this would happen since it was present during pregnancy as well (the comments, I mean). I cannot recall ever mentioning anything about perfect stranger's parenting skills to their face before in my entire life. Maybe it is something that people feel entitled to once they have raised/are raising children? I don't know.
For example, at the grocery store the other day a lady in the checkout line commented on "how proud she was of me that I put mittens on my baby". I know she was trying to be nice and all, but really? You're proud of me? You don't even know me. I could have lined those mittens with razor blades or doused them in whisky before I left my house. (I would NEVER do either, BTW, so move your hand away from the mouse and the 'comment' button and get a hold of yourself.)
Then, THEN, on the way out of the grocery store, an older gentleman tells me that I should have put the baby carrier in a cart and pushed him around instead of carrying him. I politely told him, "Eh, just picking up some gift cards, no need! Plus it builds my muscles this way! (har har)". He responded with, "It doesn't build muscles, it just makes you tired". Dude, let it go. As if waking up at 5am to feed my baby doesn't make me tired enough.
