Seriously?

Why is it that old people are like obsessed with feeding infants so unhealthy? Or maybe its just my mil? But it drives me crazy how she is always wanting to give him sugar and ice cream and candy ( hes 6 months btw and already a big boy 24lb and 28.5 inches long) so i definitely want him to eat as healthy as possible. She also seems to hate the fact i only give him organic baby food and usually stuff like kale and spinach and quinoa and avacado and stuff like that and wants him to have only fruits. Today i posted a pic of him eating some baby food out of a silicone mesh feeder and she messaged me saying how he probably loved that ice cream, i told her no it was baby food and i probably would never give him that much sugar this young. I mean diabetes runs in my family plus childhood obesity is serious. And even myself if i eat too much sugar it makes me sick since i try to stay away from it. Its just so annoying. She also said i should taste my baby's food before i give it to him and if i don't like it then i shouldn't feed it to him. And she said she doesn't agree with keeping babies rear facing till 2 years old. Literally wtf?! She must be a god damn expert🙄🙄🙄
