And a solicitor for the 31-year-old woman, who cannot be named for legal reasons, told the court in Dumfries this week that an assurance had been given that there would be no repetition.
The mother, from Ayr, admitted drinking excess alcohol while responsible for the children aged six to five weeks and exposing then in a manner likely to cause them unnecessary suffering to health, as well as picking up the five week old infant and dropping her onto the floor, resulting in her striking her head.
She also admitted assaulting ambulance staff at a holiday caravan at Southerness last month and preventing them giving assistance to the injured baby with police having to be called in before the child could be taken to Dumfries Infirmary.
The court was told that when taken to hospital it was found that the infant had a slight fracture of the skull, but it appeared there would be no lasting damage.
Sheriff Brian Mohan imposed a community payback order with conditions that the mother be under supervision for 12 months and carry out 100 hours unpaid work.
