My once energetic 16 month old is suddenly tired all the time. In the past week she went from 1 nap a day to 2 maybe 3 long naps a day. Last night she fell asleep right after dinner at 6 and slept until 6 this morning. She has dark circles around her eyes. She cried a lot when she’s awake and just wants to lay around and be snuggled. She isn’t showing any symptoms of being sick or teething. I’m going to call the pediatrician in the morning I just wanted to check and see if it’s normal or if anyone would know what’s causing it.
