Congrats on the pregnancy!

It is possible it's the pregnancy making her more clingy. My dd became impossibly clingy during pregnancy and moved back into our bed and would only nap if I napped too. It actually got worse and worse until the baby arrived and then bam! She became little miss independent! Then she didn't want me to do anything for her!

I found it best to go with it and give her all the extra attention, because it's your last chance before baby comes, and I have really special memories of that time now.

Good luck!
