Nap wake-up?

Katie
Does anyone else's little love wake after 45 min of nap, chat and play a little for 10/15 min then go back out for another hour or so? My 5 month old has been doing this for his naps so I'm not sure if it's just him trying to figure out his sleep patterns. He doesn't cry which is good but I'm just not sure if this is normal or just my guy lol.
