I'm confused, my Mum-friends are confused too (either first timers like me, or had kids so long ago they can't remember), so help please....DD is 2 next week: I thought she had all her teeth, and was done with teething, because someone told me they only get one set of molars (ie four of them altogether) first time around. But I keep seeing posts about 2-3 year olds teething? Someone straighten me out!
