Do child abductions occur in Ireland?

I'm only asking this because today I saw a mother in the self-checkout line at the grocery store. I guess someone told her there was a hot deal on canned soda and she took off back down the aisles to get some more. When doing this she left her young son (probably two years old) sitting in his stroller at the checkout. I'd say she was gone for a full five minutes. Thankfully he was okay and I know this because I stared at him the entire time to make sure! I see this kind of behaviour all the time. People walking down a crowded Henry Street not paying attention to their young child wandering along behind them. One day we were in Howth and there was a tiny baby in a stroller just sitting on the sidewalk. It didn't seem this child belonged to anyone, so of course I was freaking out. I made Wes stand there with me until we saw some people (that I can only assume were the parents) got out of a nearby parked car and put the baby inside. WTF!? It only takes a second for that child to be snatched up! I never noticed people doing this kind of thing in the US, even in the grocery store in my parent's small town. Maybe I'm just being paranoid...
