Oh also I started my son on baby cereal at 4 months but he didn't like it and kept pushing it out of his mouth. He didn't lose the tongue thrust reflex yet so I didn't try again . at 5 months he lost that reflex so feeding him baby cereal was super easy
I started mine at 6 months but I heard some people start at 5 months it all depends what your baby is ready for. They will let you know if they don't like it by refusing to open their mouth.It's all just for fun anyway at this point .
Awesome thank you both @bianca_rose @mamahoude
