My 8 months old doesn’t drink from cup

I bought 360! A one with straw

And finally sippy cup and he is not accepting any of them I tried many times since he is 6 months and no hope

And also he doesn’t hold the bottle by himself! He used to hold it when he was younger but not anymore

Should I be worried

Did I make something wrong?

Plz don’t shame I’m a FTM
