My 2 year old is heavily reliant on the dummy I.e asking all the time for it, and especially reliant for sleep. Is naughty, agitated without it. But 'dummy teeth' are emerging and I'm desperate to wean effectively without causing severe distress (he has extreme abandonment fear I.e extreme clinginess to me extreme meltdowns if I go upstairs to the loo etc) any ideas for quick and effective weaning?
