we mainly rely on the good old nipples, lol... we do use a binki though sometimes. Like those times shes sucking and can't eat anymore. Riley does this thing where she'll eat and eat and throw up everywhere then eat and eat...and the whole eat and throw up process continues till we're both exausted. I couldn't take it. Turns out all she wanted was to suck on something and not eat. She'll use the binki until she finds her thumb which we are encouraging now. She doesn't quite get it now but her brothers I did the same with it. They both stopped using a binki by 6 months by their own choice after they found their thumbs. Shes currently getting a thooth and the biting on the binki is helping. She doesn't bite my boob alot because shes been taking it out on that binki. lol
