baby sleeping pattern

I’m a bit concerned about my son's sleeping habits and how they might affect his development. He's currently 2.5 months old, and his sleeping pattern seems a bit irregular compared to what I've read or heard from other parents. He tends to have short naps during the day, maybe 30 minutes to an hour at most, and then he'll have one longer nap, usually in the late afternoon or early evening. At night, he usually sleeps for about 3-4 hours at a time, wakes up for a feeding, and then goes back to sleep for another stretch. I’ve read that babies his age should be sleeping longer stretches at night and taking longer naps during the day. Should I be worried that his sleeping pattern might hinder his development? Or is this normal for a baby his age?
