I found dummies to be a lifesaver!! DD1 quit hers at 6 months but the other 2 kids had to be made quit LOL Riley especially was an addict but you know what he's 4 now and hasn't had a dummy for over a yr and it hasn't affected his life at all.
Mine all loved happy baby cheap ones, I know there have been some issues with them lately but I never had a problem and they were really cheap and available everywhere so I had no hassles getting one if we accidentally went out without one or lost one.
