DUMMIES... Xander used them, Declan wouldnt go NEAR them, spat them out whenever we tried to settle him with them, and xander would run off with them, as we "traded" his for a toy when he turned 18m... Anneliese sucks on hers for a lil while, then spits them out... Its all personal preference, im lucky ours like the cheapie $1.60 ones
