Excessive Breastfeeding?

Beebee

LO is on my breast every 30min. She says "boob" and wants to nurse. Though there are times when she does it for attention, comfort. Sometimes I don't mind and others I say not now and she cries. I don't mind nursing until she's 2 but I think she over doing it. Anyone dealing with this? Do I confuse her if at times I refuse?
