just wondering if anyone else's baby does this?

So my LO will be turning 14 weeks tomorrow. He started sleeping like an ANGEl, for almost two weeks he would go to sleep around 8:00 pm and sleep until 6:30-7:00 am. It was wonderful haha. Now, the past couple of nights he goes to sleep around 8:00 pm and the at 4;30 am I hear him on the monitor. He isn't crying just talking and cooing. I check on him via the video monitor and he's just looking around. My husband and I watch him for about 30 mins and then he starts to put himself back to sleep. We haven't been going in to get him because he's not upset, he's perfectly content. Just wondering if anyone else's baby does this and if you go in to feed them or try to put them back to sleep. Thanks in advance for your input :)
