4 month sleep habbit...

Kari
So everyone is posting about how their 4 month old sleeping habits have changed and not for the better... 
My 4 month old has changed but... I dont know if it's normal... Ever since he was a new born he would sleep all through the night. He would wake up at 3 in the morning to eat then go right back to sleep. Then started sleeping until 5 in the morning waking up for a bottle and going back to sleep. 
Now he's to the point to where he sleeps in until 6:30/7:00 in the morning. (Mind you he goes to bed anywhere between 8:30/9:00) 
And he takes a few naps during the day. Nothing very long. His morning nap is the longest... 
Is this normal??? I feel like he's sleeping too much??
