I think you're fine too,I only dropped my ds's bottle when he was a little over 2,as he too was just drinking and not soothing. Had bought him several "proper" cups (ie Noddy one,snowman one etc) which he would choose for his milk each day. He liked the idea but it did take quite a while for him to actually do anything but take a tiny sip though,lol!! I didn't push him to drink more,just made it clear that was basically all I was offering him!! He's now just turned 3,and still has a cup of cold milk at bedtime (strangely has never accepted warm in the new cups) which he drinks well, and sometimes even asks for it during the day too!!
