For those whose LO are STTN, did it happen suddenly or gradually? With my DD who is 2.5, she suddenly slept 7 hrs one night at 4 wks old. From then on, she slept longer and longer until she slept 12 hours a night. With my DS who is 8 wks old, be still gets up every 3 hrs for the most part. Sometimes he'll go a random 4 or 4.5 hour stretch. I just wondered if most people's LOs suddenly started STTN or gradually elf longer and longer until they were STTN.
Re: STTN: gradual or sudden?
IMO, it has a lot to do with age but also how their day is (when and how long they nap, as well as when their last feeding of the day is).
How are his naps? When does he "go to bed for the night" (i.e. does he have a bedtime? When is his last feeding?)
