I must be the worst mom ever!!!

So my son is 16 weeks old.... I let him watch TV, I put him down to sleep on his stomach, with a blanket! I make him cry it out when possible.... I also have introduced cereal and apples, and plan to introduce peanut butter at 6 months.... Im so tired of all these opinions like these mom's got the right answers, they got it allllllllll figured out! It's amazing that I have a 5 year old, who is alive and thriving and sooooo smart. It's amazing that any of us are still alive today, since our mom's and grandmother's did NOT have all these stupid rules.... Smh at all this... And smh at myself for letting y'all get to me.....
