Is it normal for toddler to want to be breastfeed so much?

Claire

Few months ago my little one went cold Turkey. She turned 1 in October and in a snapped of a finger, she rejected the breast.... end result my milk stopped. 3 weeks ago she started asking for it. Like badly doesn't care where we are she'll stick her hand in my shirt. Boob is all she wants and knows, of course i give it to her eventhough i know shes not getting anything. Im trying to understand if this is normal. I am due to give birth at the end of March. Could she be doing this for comfort. Teething? What's going on my little munchkin?
