9 month old- 3 short naps 🤷‍♀️

My 9 month old has never been a great napper unless contact napping. He is currently taking 3 naps a day that are only 30-45 min, unless I do a contact nap that lasts longer. He seems happy during his wake windows and is sleeping through the night in his crib for the most part. Any other 9 month olds nap like this? I know most have already transitioned to two naps but I don’t see us getting there yet with these short naps. I’m worried it’s not enough daytime sleep! Any advice on stretching naps or working to transition to two longer naps when you have a micro napper! 😣 I would obviously love more than 30 min to get things done but do I just go with this if it’s working and night sleep is going well? Appreciate any help!!
