LO has been STTN for a couple of months. Suddenly for the past three nights she is fighting going town to sleep and waking up upset several times a night. I don't think she's teething or anything else is wrong. What puts her to sleep the best is nursing but I don't want to create a MOTN nursing habit. Should I just nurse her when she wakes up at night and hope she goes back to a normal sleeping pattern? If your LO went through this how long did it last?
