Topic: Baby Bottle

So our tot still take a 1 bottle of milk a day (mostly for winding down in the evening or when not feeling so great, I have found a bottle of warm milk for a teething baby is purely a magical cure) My question is, what bottle would you recommend? The best type of orthodontic bottle? (he does those rim cups and can drink from regular spoutless cups) I will only be buying two so any recommendations would be great/
