Jodie has 4 teeth coming through she has usually got a great sleeping pattern. She wakes 7-8.30am and has a half hour nap after dinner. She goes to bed 6.30-7.30ish. which is great as she hates waking up so one long sleep is better for her. Since she has started teething again she is awake untill 12 midnight and awake again at 4.00am. is this normall as she is usually a good sleeper. Does teething mess things up.
