Tell me how long your 16 month old is awake for at a time, I know it’ll vary but I’m struggling to find the sweet spot for my DS since transitioning to one nap. He’s only averaging about 45 mins-1h15m nap a day at the moment. He’s up for about 5 hours before going for a sleep. Most nights he sleeps through so maybe he just needs less daytime sleep than others 🤷♀️ constant guessing game!
