Helen Murray, 38, from Dobson Walk, Corby, Northamptonshire, pulled across a main road into the path of an oncoming transit van on the A427 in Corby on April 28 last year.
Her son Luke Murray and his friend Terence McMahon, both 13, were both killed in the crash, along with Luke's six-month old German Shepherd puppy Remus.
She had previously denied one charge of driving without due care and attention.
At Northampton Magistrates Court today the prosecution said she showed "inattention" when she pulling into the path of the van.
Sentencing magistrate Mr Baker said: "The outcome of this case must be the least of the concerns with the other matters that we all know of.
"The punishment very rarely becomes relevant here."
She was banned from driving for nine months and fined £500.
