Anyone else's newborn not sleep very much?

We use the tracking on Glow and he averages around 11-12 hours a day. He's often awake for 2-3 hours between some naps (not all) and he doesn't sleep for longer than 3 hour periods. My midwife says babies take the sleep they need but I'd still love to hear about other mamas in this situation. He was awake for 5 hours (in one go) the other day and only went down because his grandparents took him for a walk. Luckily he goes down fairly easily after each feed at night (every 90-120 mins 🙄). I'm breastfeeding.
