My four month old has never been a champion sleeper, but my app tells me he consistently gets between 10-11 hours a day when it should apparently be 14. He’s a very happy baby, not fussing or seeming overtired. I follow his sleep cues. Should I be doing more to get him to sleep or is this just him and he’s low sleep needs? Worried I’m harming his development by not trying harder to reach that elusive 14 hours. Anyone else had a baby that didn’t need nearly as much sleep as the guidance says? Or am I being a bad mum and do I need advice?
