Sorry for the dramatic subject line but I need some tips!
My 7 months old continues to stick her fingers to the back of her throat and then...yes, pukes everywhere.
I mentioned it to the Pedi MD and she said, "Oh, she's dicovering her mouth, just re-direct her." That is not working! I could keep my eyes on her every second, but unless I am holding her hands she is too quick. She doesn't do this all the time but she does it enough that I am starting to wonder if something else is going on. Is her throat sore (everyday for the past month, with NO temp), is her mouth itching??? She isn't teething yet.
She's discovered that if she shoves her fingers back there, something weird happens and even better-mommy freaks out!!! It's normal. Annoying but normal. Distract, redirect, and just say yuckies! and remove her fingers if you catch her in time. She'll grow out of it.
My son went through a similar phase three years ago and occasionally does it sometimes now but now he chews the skin off hid fingers. Not to throw up but because he wants to stimulate himself by having something in his mouth. Let me be a bit more specific he was diagnosed with sensory processing disorder at around 16mths. SPD basically means children with this disorder need constant stimulus and they resort to any measure to get it. He begun occupational therapy and the therapist told us yes it is discovery but its also his way of giving himself input in his mouth on constant basis. Her recommendation was put something sour on his fingers to stop him from making himself gag and she gave us what are called chews. Their basically gummy rubber chews that are for older kids and they provide different textures for children to chew on. They are made for all ages look it up on google type in sensory chews or special needs toys. It worked for us hope this helps good luck
