What am I doing wrong

AB

Ok what am I doing wrong here ? My son is now 1 year old and I’m still feeding him with his bottle . I tried giving him a sippy cup but he refused. He can drink out of a regular cup but it’s too messy and he spills half of it and I do have to feed him as well. I need some advice please😩😩😩 I guess I should have started training him sooner 😩😩😩
