Well I desperately wanted Megan to take a paci instead of sucking her thumb because the paci is ultimately easier to rid of. She refused and loves her thumb.
I didn't even try intro'ing a lovey to her because she's not severely attached to me like Kylie was. 
Well lately Megan has to hold on to something when sucking her thumb. She'd grab on to my shirt, anything so I bought her a special little lovey blanket just for her. This morning she refluxed on her lovey so I had to put it in the wash and her "back up" lovey is at daycare. So she didn't have it. She was sucking her thumb and so desperately wanted her lovey that she grabbed on to her bibs to give her that satisfaction. It was hilarious. See picture below. Not a great picture to capture the moment but you can kind of see what she's doing.
Please excuse the mess on the floor. 
Btw, after I took this picture she got tired of using her bibs as her lovey and crawled over to where her sister just took off her pajamas and she used them as her lovey. Didn't get a picture of that though.
