Kalwant Singh Dhanda was barred from working with children by government ministers after Disclosure Scotland checks.
During a hearing of the Nursing and Midwifery Council the panel was shown photographs of the result one attack on a four-year-old child that left a mark on the skin.
The nurse claimed it was a small heat mark.
But evidence from a doctor found the mark was "... suggestive of an inflicted injury (imprint) from an object or a hand."
The incidents happened in Glasgow, outwith Mr Dhanda's place of work, and were investigated by Strathclyde Police.
The nurse was charged by police for two assaults on a four-year-old and a five-year-old, on an unknown date prior to March 12 2011.
The hearing was told no court action was taken because of the age of the children.
And there was no conviction because the charges were dropped.
The assault of the four-year-old was proven by the panel due to "overwhelming" evidence but the second was found "not proved".
Andrew Gibson, representing the NMC, said assaulting such a young child was "incompatible" with being on the nursing register, that there was no evidence of remorse from the nurse and that his action had brought the nursing profession into "disrepute".
A statement by the NMC said: "The public do not expect registered nurses to assault children and there was no doubt that this type of conduct falls below that expected of a registered nurse.
"In the panel's judgment the public would have serious concerns about a nurse who behaved in this manner, causing injuries to a small child and thereafter failing to notify the regulatory body that they had been charged with such an offence.
"Your actions have clearly brought the profession into disrepute in the past.
"The panel has
heard no evidence of insight, remorse or remediation.
"This has lead the panel to conclude that you may in the future be liable to bring the profession into disrepute again."
Ms Ram, solicitor representing the nurse, described the attack on the four-year-old as an isolated incident and said Mr Dhanda had trained as a nurse because he, "wanted to make a difference."
