Jack likes to stick his finger up his nose. A lot. Where a baby will have a pacifier or a toddler may suck on his thumb, our Jack shoves his finger up his nose like it's a thing of comfort. He'll sit on the couch, digit up the nostril, eyes glazed watching Spongebob Squarepants and I think "good lord I'm a terrible mother".
I have tried all kinds of tactics to stop it:
Polite reasoning: Take your finger out please, you'll spread germs
Pleading: PLEASE don't put your finger up your nose
Anger: Get the finger out NOW
Humour: Are you digging for gold?
Rage: FINGER. OUT. NOW
Threats: If you don't get your finger out, Spongebob's going off
Bargaining: If you stop doing it I'll give you cake
More humour: Your finger will fall off and then where will you be?
And so on
At the zoo this fall I whispered to him "take your finger out of your nose!" and the lady next to me said "but it fits so well!" Maybe that's my solution. I'll make him wear rubber gloves.
