When did your baby start using their hands?

My son is 5 months & he won't use his hands. He chews on them, his reflexes are good (he grips anything held to his fingers), & he plays with them by clasping them or grabbing his toes. But, he won't hold a toy, I have to hold it for him. He can hold it if I give it to him & will hold onto it, but he won't do it by himself. Sometimes, he won't even take the toy; I have to hold it & play with it while he watches or he screams. He won't try to hold his bottle & he doesn't reach for anything. He can roll over, he can almost sit up by himself, he pulls up to stand, & he's babbling with consonants so it's weird when I see babies younger than him playing with toys & reaching for mommy. I can understand not holding his bottle since he only has maybe 4 a week. Did anybody else's child do things like this? I'm not worried, just wondering if this is normal.
