The mother and baby run over in a freak accident in Downpatrick are recovering in hospital where their condition is stable.
Diane Herron, from Newcastle, and her 10-week-old son Jack were comforted by her husband James, a businessman, and other close family members at Belfast's Royal Victoria Hospital after the horrific incident.
Mrs Herron was on her way to Downe In The Mouth dental surgery on Irish Street for an appointment when a broken down horse transporter rolled down the hill into her path as she was carrying her baby in a car seat.
Reports claim the woman's husband was with her at the time and witnessed the entire incident.
While the baby was quickly rescued from his car seat from underneath the lorry, it was some time before his mother was freed by emergency services.
The baby was cared for by staff at the dental surgery before his transfer to hospital.
One member of staff described their shock at witnessing the incident outside their front door: "We were all pretty shook up over it, I never want to go through that again".
Paul Symington, editor of the Down Recorder newspaper, said the mother did not see the horse lorry rolling back on her and was "just clobbered" by it.
