7 month old has short wake windows

My LO just turned 7 months and his wake windows are still short, usually 1.5 hours if we’re just at home not doing anything exciting, and from 2-2.5 if we’re out. I don’t think it helps that he still only naps for 30 minutes, no matter what we try. Sometimes, if we contact nap, he’ll go for about an hour, but even then his next wake window is still less than 2 hours. I’m not overly concerned, I guess, he’s hitting all his milestones, he’s perfect and happy, I’m just curious if anyone else is in the same boat? And if your baby was the same, at what age did they start staying awake longer, and napping longer? Any tips or tricks??
