Everyone in my due date group refers to their babies now as having naps throughout the day etc and being alert and awake for long periods in between them and I've realised that something might be up. My 11 week old definitely doesn't have nap times he is basically always asleep, he'll wake up for maybe 10/20 minutes here and there to feed, poo or cry but he goes straight back to sleep. He is never awake for anywhere near an hour! He sleeps all day and all night just with very short little periods of being awake. He's never particularly happy or alert when awake more crying, fussing, feeding or pooing and then back to sleep. He's still very newborn-esque. His weight gain is fine so I've assumed it's normal until comparing to others. Are some babies like this? Or do I need to be calling the health visitor?
