Advice Anyone?

I know that by the looks of her, it will be hard to believe that she is causing me some major grief, but anyone that's been around her for very long, will not be surprised at all.

I have spent the last few weeks completely smitten by her and her emerging personality. She is fun to talk to, the things she thinks to say crack me up. She loves her 'lips' (chapstick), her pa and grandma's, her dresses, her movies, her cousins (big and little), and lots of other very girly things. She has grown up so much lately, and I'm crazy proud of her. She relinquished her nighttime bottle (no judging, she's barely 2.5) with relative ease and was potty trained within two days last weekend.

So what's the cause for grief? Bed time.

My kids have always been great about going to bed. Carson's down at 7:30pm, bottle and binky and he's a goner. Spencer and Sophie anytime between 8-8:30. A month ago, I gave her a bottle, tucked them both in, shut the door and that was it. Easy. But, in the last week or so, she's completely reverted. She yells and throws herself all over the floor when I say it's time to get ready for bed. Tonight, she ran through the house (times like this I love only being in a double wide, I only had to haul the 50lb kicking, screaming toddler a few feet to get her back to her room) and then yelled at me "I not see you! I not ever like you!" It's being coming a huge battle.

I have no problem letting her cry it out, but since the kids are all sharing a room, that doesn't work out so well for her brothers. Tonight, after letting her cry for a good 10 minutes, she came to her door, begging for her dad and I spent a good 3 minutes convincing her to let me lay with her. As I tucked her in and quietly sang to her, she was asleep after just a few minutes. I laid there next to her and wondered if I need to give a little in the situation or will that just lead to a bad habit? Is it a small sacrifice considering all the growing up she's done lately? I don't mind laying with her or sitting in her room, but I don't want it to become a regular thing. Do I regress in this one area since there's been so much progression in all the others?

I know that this stage is fleeting, as is her age. I don't mind giving up some of my time to spend a few extra minutes with my kids, but, I do worry about creating a habit that will have to be eventually broken. Ugh, I hope I don't sound heartless! It's just hard to regress.

Any advice?
