Are you more likely to judge someone because they feed their children

So I have a one year old and currently pregnant with baby #2, but EVERYTIME I go over to my husbands family they always have something to say about how I choose to feed my son! So I try hard to feed him pretty healthy like atleast some fruits and veggies with each meal and I make home cooked food so to me that's normal, occasionally I'll do like chicken nuggets or chicken tenders and he does get treats here and there but he's still a baby he just turned one! So whenever we go out I have his little meals packed especially if we're spending the day there. Why? Because they only feed their kids junk food! They put soda in bottles! They eat chips and cookies before even learning what fruits and vegetables are, and this is for the babies! They order happy meals for his 6 month old cousin! The kids are so overweight and never eat anything with any nutritional value yet they have the nerve to judge me for feeding my child they way they should be fed! I can't stand it because it's everyone who says something! Grandma, aunts, cousins! It's so hard not to go off on them and the they're always laughing saying "oh we can't give the baby that his mom will get mad, poor baby!" OR they go right ahead and give him all this junk without my permission! What should I do!?
