My DD is 13 months old and has never been a great sleeper. Lately she has been waking for 4 hours in the middle of the night. She won't go back down and wants to be held the whole time. She does go back to sleep much quicker for her dad but will cry and protest a lot. She often skips her afternoon nap so is extremely overtired by bedtime and goes down between 6-7. She still takes a while to go down. We haven't been able to drop the first nap as she wakes around 5am and is falling asleep by 9/10am. She usually does a morning nap of 1 hour and then won't go down for the second one, even if we try for two hours. Please help, I am at the end of my tether with exhaustion 😓
