Cathy O'Neill is calling for a change in breastfeeding legislation.
The petition began after the DUP's Sammy Wilson accused breastfeeding mums of exhibitionism.
She started a petition to bring Northern Ireland's legislation in line with Scotland's.
This would make it an offence to stop a child from being fed in a public place.
LISTEN: Michelle Major, a petition supporter who will be with Cathy at Stormont today, has been speaking to Q Radio's Iveren McCallion.
