My DD has used a dummy since day 1 in the hospital. She did go through a short phase of it dropping out in bed & not being able to put it back in but it wasn't enough of a problem that it would wake her through the night (I was lucky to have a baby who slept through from 6pm til 7am from 2 weeks old!) it was usually when I was putting her off to sleep. So I know the dummy dropping out of her mouth didn't cause her stress because she slept straight through it!! haha I know it can be a problem for some though, I think thats the only down side to dummies, until its time to take them away!!!

DD is now 2yrs 8 months old & she still uses dummies at bed time & sometimes if she's sick for comfort but thats not often at all. I honestly dont mind her using them, I know she will eventually give them up but at the moment we're happy the way things are.

I put about 6 dummies in her bed at night so she can always find one if needed

I hope this helped you, good luck making your decision
