So my son just turned 1 and He’s been strictly breastfeeding, I been trying to have him eat baby food but he probably will only eat one a day then breastfeed thru out the day, he doesn’t care for baby food all he wants is breast milk and I have no idea how to get him to eat. He’s picky with everything unless it’s breast milk

Then I been trying to have him drink from a sippy cup and the 360 sippy cup that’s like a normal cup and he doesn’t know how to drink from it, instead he bites it & it’s understandable because it’s all new to him but I don’t know how I get him to learn to drink from it. I just don’t know what type of routine I should do to stop breastfeeding and get him into the sippy cup and eating food instead. I need some advice, this is really hard and frustrating 😩
