I use happy baby as they don't hug the mouth and trap dribble. Also cheap and readily available.

DS1 gave his to santa (white ones) so now DS2 is the only one who has them (blue ones), and he will be giving his to Santa at the end of the year. The dummies are for bedtime only, unless he hurts himself and needs to be calmed down.

We are in the unusual situation where after a bout in hospital at 4 months old DS2 refused the dummy (YAY) but then we reintroduced it at 8 months just so I could get some sleep. Best thing I ever did as I was waking up to settle him every hour or so.
