Hi B.,
Just trust your instincts, what does your heart tell you to do? Listen to your heart, then follow it!
It's OK to make mistakes in parenting. That's how we learn what not to do with the next one. LOL!. Those are the times when you can look back and laugh because you can't believe you were worrying about that, or what you did, what they did.
Everyone's situation is different. Every child is different. Each family situation is different. My hubby worked first shift and I worked third shift when our son was born. I got to sleep when and if he slept. It's just that. You do what you have to do.
If you need to change your daughter';s sleeping habit for a reason then by all means do so., She'll let you know if it's not going to work or not. And then you move on to plan B. If it works, you are good to go.
