Alittle help!! 30 minute naps 😖

So I am not truly sure I have an issue here but I'd like to get some advice and other points of view... I have a beautiful baby girl who is 5 months old and such a happy baby all the time she is exclusively breastfed and we recently started solids (no rice or oatmeal just fruits and veggies) she sits up unassisted and is currently working on the crawling 😯 anyway she is a pretty good sleeper at night solid bedtime routine since 6 weeks feed,bath, jammies and in bed by 645-7pm wakes between 11pm-1am for a feed then sleeps until 6am she'll eat and then be ready for a nap at about 730am where she'll sleep until 830-9am which is wonderful!! But that's where it ends for the good naps the rest of the day is 30 minute naps and I'm desperately trying to figure out how extend them, she is in her own room put down awake for naps and shh-pat until she settles enough to sleep with white noise (usually 5-10 minutes) she doesn't wake grumpy or crying always smiling and happy to see me but I am noticing that she does yawn and seem alittle tired 30 minutes after she's been up, she even sometimes goes back down at the 45 minute mark her usual wake time is 2 hours..with 3 hours between feedings we are currently doing the Eat Play Sleep and it has been working wonderfully except for naps

Sorry for such a lengthy post but is this something she will eventually grow out of? Or are some.babies just short nappers!?
