Baby won’t sleep during the day!?!?

Shawna

My May baby will not sleep during the day. He sleeps through the night which is great but does not get enough sleep in a 24-hour time period; less than 15 hours a day. This week, it has been less than 10 hours with only 20 minute naps every 2.5 hours. I am going insane!! He is growing like a weed and his personality is always the same but I am scared this will effect him in the long run. Is anyone else in this boat?
