DD is 6mo but has been fighting sleep on a daily basis for a couple of months at least. I'm not expecting her to get into any sort of routine, but when she begins to show signs of tiredness, I do everything I can to let her sleep. It's a constant cycle of her refusing, getting overtired, and then still continuing to fight every single opportunity of a daytime nap. If I'm lucky, she'll get one 15 minute in during lunchtime, and then stays grumpy the rest of the day from tiredness until she finally falls asleep around 9/10pm. It's exhausting for both of us and I can't get anything done because she'll start screaming if I leave her alone. Any tips?
