So our youngest is 16 months, her big sibling dropped their naps completely by 12 months but then would sleep 6.30-7am. On the odd days she hasn’t had a nap she sleeps 7-8am, however even a 40 minute nap and I’m struggling to get her asleep before 9. Not sure whether to drop the short nap she has but she does become unsettled around 4-5pm if hasn’t had any nap
