B.R.
I completely agree with the last post. I went through the same thing, and it's totally normal for any little break in routine to change the behavior of children this age. I'm going to guess that you or someone else probably held her a lot while she was sick (as I did and as well you should have) and all she probably remembers is that you holding her made her feel a little better. Now that she's better, she still wants that good feeling of being held. You can't force her or let her cry it out, but you do want to put her down as soon as she is calm. Then, if she starts to cry again, pick her up again. You may do this 10 or 20 times, but it should work after a few days. By picking her up every time she needs you you will assure her that you will always be there when she needs you, and putting her down as soon as she's fine will encourage her to be okay on her own. It will seem silly and repetitive, but unless there is some underlying issue it should work after a max of three days. I used a similar method to get my daughter to go to sleep on her own because I wasn't feeling the whole cry it out thing, but I did see the value of her learning to sleep on her own- and now people are absolutely amazed at not only her ability to fall asleep with no fuss, but her willingness to go to bed- and she has never been an "easy" baby. Good luck, stay strong, and try not to get frustrated.
One last thing- my daughter every once in a while will decide that she just needs to be held. Thankfully, she's past the point where one little change will create a habit, so I can do that once in a while, but she is heavy and I hate to sit still for long. I have a peanut shell (a baby sling that can be used until late toddlerhood) and on those rare days I put her in it and she can snuggle with me while I do stuff.
