...because he's always pulling it out and I don't know how to stop it. What's heartbreaking is that it's obviously a sign of affection (and he keeps holding it when I give him a bottle, or cuddle him before bed), but he doesn't realise how much it hurts sometimes! Keeping it out of his way is difficult when I pick him up even though it's not very long. Saying 'no' just seems to amuse him.
Any tips? Is it something they grow out of?
