4 week growth spurt...?

K

FTM here... Our little guy was born at 41+1. Little one is usually spot on with waking every 3-3.5 hours for feedings. But the last two days he has been sleeping between feedings much longer than normal - like 4-5 hours. Still having a good number of wet diapers, but diapers aren’t like “heavy” wet. Anyone else experience this? I’m paranoid 😭. Checked him with a rectal thermometer and he doesn’t have a fever.
