Yes, it is hard, and yes, you and your daughter will be perfectly fine....better than fine- you will both be getting the sleep you desperately need! Like you said- she doesn't need anything...but sleep, maybe!!! At 2, she should be sleeping through the night. If you listen, you can hear the difference between pissed and panicked...pissed off is easy to handle, and if you feel she has crossed the line into panicked- go get her, and don't feel bad about it. The hubbs & I were just talking about this, and when I went back to work after my 1st born, nights and weekends, my hubby saw that she really needed/wanted to sleep, so keeping her up until I got home was doing more harm than good. So on the advice of my mom, he let her cio for an hour. The deal was, if she went longer than an hour, he would go get her- but she never went that long. The crying was mostly off and on, and I know hubby would have gone to her if the cry was one of those panicked cries. Babies need to learn to self-soothe, and sometimes crying and fussing is a part of that- don't let others make you think you are scarring your child for life- you know your baby and yourself and you will do what you need to do. At her age, you should create a bedtime routine that is low-key, loving, like stories, singing songs, but that is firm too- "okay, now it's time for bed, goodnight, I love you" aaaand done. Kids will push it to the limit- why not? It's their job! So you have to set the limit, in a loving way, so she and you can get the sleep you need. Good luck, and have a good night's sleep!!!
