she won't move for anyone lol!

My girl kicks like crazy all the time, but as soon as I put someone's hand on my stomach, she will not move again lmao! I feel so bad my husband has only felt her once. My sister was sitting next to me at dinner last night and as soon as I put her hand there she stopped! She is making me look bad lol!!! Anyone else experience this? 33 weeks and 1,day!! 7 weeks to go!!
