Clingy younger children..

So I'm 35+5 and for the past God knows how long, my youngest 2 years has been nothing but clingy. She follows me everywhere and I mean everywhere! She has to be sat on me or next to me so she's touching me. She won't go off on her own. It's really starting to irritate me, not to sound horrible. But I'm extremely uncomfortable the nearer I get to due date and her jumping all over me and undress my feet isn't helping. I'm also going to be breast feeding so I'm worried about her whilst I'm feeding baby. Anyone else have a young one like this with them?
