oh Nicole hon dont be hard on yourself, it is perfectly normal still to have him in a cot, it honestly sounds like he is not ready.
Julia my first wasnt ready when we put her in her bed because our 3 month old needed her cot but we needed to do it. It was a struggle, we didnt give up the bottles til a bit later. Try not to listen what others say I know friends who have the children in a cot stil at 3. Can you have fun with him on his bed so he can see its fun? We got a nightlight for Tara that she picked out when we moved her to a big bed and that really helped too, you may already have one though, but it was a great distraction as it changed colour and was cute (Charges during the day in another room and when in the kids room runs all night not attached to any electricity.
