Do you see a problem with this?

My daughter is 13 months old with 6 teeth. We had steak for dinner tonight from Longhorn and we got her a kid steak from the kids menu. We cut it up in very small pieces and she chewed it just fine. My husband posted a pic of her eating her first steak on FaceBook. My sister in law texted me happy bday and then asked what the joke was about my baby eating steak. I said there is no joke, it's what she ate for dinner. She continued to text me that she couldn't even take me seriously and then called my husband to inquire further. She has two kids and works at a daycare and her 4 year old doesn't even eat steak. I found myself getting pissed because I've seen her kids eating cheese puffs and other garbage that has zero nutrition on a regular basis. I'm a nurse, I don't say anything every time they run to urgent care and the ER for petty things. I don't say anything to her about never moving out of her parents house even though she got married and had two kids and has made no effort to be independent. I mind my business and don't worry how she parents. Is giving a 13 month old steak that unheard of? Sorry for the rant. I'm just really annoyed and my husband doesn't get why it bothers me so much.
