how do you feel okay with your decision?

Sadie
I know that this is literally what parenting is but how do you ever come to terms with that the decision you make is the right one and you are doing right by your child? My baby has been spitting up really bad on his formula and I've tried many things and nothing seems to work. I've thought about adding baby rice cereal to his bottles but he's only 7 weeks old some people are telling me yes they did it and it worked some say it's horrible that I will hurt his stomach long term. And I just don't like seeing my son cry due to stomach issues I'm willing to try anything to have him happy but how do I make this decision? What if I choose the wrong one and it hurts him?
