Night one.

Tonight is the first night we are trying sleep training with my daughter. So far I put her down and she cried for a half hour and then fell asleep. My question is if she wakes up what do I do? Do I just let her cry until she falls asleep again? Do I not get her no matter what until it's time to wake up in the morning? This is so hard already I had to go upstairs and do dishes while she was crying to stop myself from running to her. 😭 I'm trying my best so I don't want to do anything to mess it up. Any advice would really help.
