naps . . . where are you!?

My 6 month old doesn't nap anymore 😭 He used to take 4 30 minute naps. He's been fighting them HARD. Yesterday he took a 2 hr nap but was awake for 4-5 hour increments. I feel like it is super long for awake time, he used to sleep after 1:30-2 hrs of being awake. Now he wants to only nurse to sleep (I don't want to nurse him to sleep and it doesn't always work) before I would just lay with him and put a binkie in and he would sleep. I have no idea what is going on, but it's been going on for a few days now. Anybody else going through this? What the heck is going on?
