My 12 week old screams non stop between 5pm and 6pm every night. This is regardless of whether we have been home all day, out all day, she has slept in the day, she has not slept in the day etc. I just can't work out what to do? She sleeps through the night. Takes 5 full feeds of 180mls of milk during the day when she is generally very settled. It is just this hour where she gets herself ridiculously worked up. Any ideas? Thank you.
