Hi there, I'm pretty sure we had 4 bottles at that age, breakfast, lunch, after PM nap and then right before bed. Normally 6-7 mths is when you look to start moving away from the DF as can interfere with night sleep.
Also teeth could be playing a huge part. Are you medicating at all? Has she popped any teeth as of yet?
Her A times are high, LO is ready to drop the CN when they are consistently doing 3 hrs A time...how long has she been at 3 hrs A?
