ok so my little boy is nearly 9 months old (tomorrow) he feeds himself his bottles now but the last couple of days as he been drinking he pulls bottle out his mouth and looks at it and tries to start playing with it he on the fastest teat available for the bottle he has ...what could be the problem ...is it normal ...or would it be time to give him a beaker with his milk in bear in mind he has 9 oz every feed but where he playing with it he probably only having 8 and half oz as it goes every where he tries putting it between his feet lol
