Jayden is doing a similar thing lately too....All I do is ask if he wants a yoghurt and he'll throw himself around and cry then say he wants custard, I'll say ok and he'll have another tantrum and say Nooooo....bot bot, D-D (bottle, dummy). I put it down to just his age and also having a new baby at home....could be teething, Jayden hasn't cut his molars yet.
Good luck, hope your DD settles down soon!
