So I'm not sure if this is "it"...
Our LO's (now 4 months exactly) began extending their nighttime sleep at around 12 weeks. Up until the middle of last week, they were mostly STTN, going down around 7pm, dream feeding at 10pm, then waking at 4-5am for a paci. They would then be up for the day between 6-7am.
For the last several nights, they have been waking up earlier and earlier for a paci (closer to 2:30 or 3am), then needing their pacis replaced every 30 minutes or so. We have been having to feed around 4 or 4:30am. On the flip side, they are sleeping in until 7.
So...is this it? It's certainly SOME sort of regression, but is the worst yet to come?
