This morning we were out shopping, my son had to use the bathroom so I take him over to the servo across the road. Walked past a car and heard a baby crying, I kept an eye on the car while my boy used the toilet, there was no one else in the servo except employees. Walked back over to the shop to ask them to announce something, they said they didn't have a PA, so I went back over to the car, baby still screaming. Couldn't see the baby because of the shades but could see it was rear facing babyseat and by the cry would say only a couple of months old. My hubby and I called the cops, cops made it there promptly but it would have been 15+ minutes since I first heard the baby crying and no one had come to check it. When the cops broke in there was also a little girl in the car maybe 2 or 3. A second cop car arrived and parked infront of the car, the mother must have seen that and FINALLY came running out just as an ambulance and nrma arrived as well. The cops called me an hour or so later to say thank you for calling them, he said the baby was ok but was a little over heated. Very impressed with the police today Child protective services will be interviewing the mother at a later date.
