S.S.
I'm just about going through the same as you! My son is 8mos now and I bought him a Nuby sippy about a week or so ago. He's starting to get the hang of it but still wants me to hold it. I've been just setting it in front of him and saying something like, "Here ya go, Bog Boy" or such. Eventually he'll pick it up and even though he's not holding it up enough or quite right , he does try. So, maybe just give him some time and be patient. About the age they start holding their bottles....it varies and depends on the child. Like the sippy my baby has just recently started doing it. My oldest son, now he was doing that at 5-6mos old! So it just depends on the child! Hang in there! He'll learn! GL!
