Best nap tips

Hi! My last NK I watched was a great sleeper for the most part and would just go down for naps. My new NF has a 8 month old who has been so hard to get down for naps recently 😅. They don’t want me to rock him so he doesn’t rely on for every nap and bedtime, he does take Binky’s but throws them out of the crib so much. Since he learned to sit up he just wants to be sitting up and kicking at nap time now. They also don’t have black out curtains so I’m not sure if that contributes but I’m not going to interfere with that lol. I play a sound machine make sure he’s fed and changed and some days he’ll just scream and cry.. they said just to let him but they also WFH so I feel bad making him cry when they are on phone calls and such for work. Any tips you’ve found over the years as Nannie’s or parents please share!! My first time really working with a child who struggles with naps. And yes he has age appropriate wake windows right now usually 2.5 before his morning nap and then 3 hours before his afternoon nap.
