is this a growth spurt?

[pipoca]

DD is 15 wks today and until 2wks ago fed at ten Pm then roughly 3 and 6 am. 2wks ago she dropped the 3am and did ten Pm til 5 or 6. Now for the last wk or so it's back to 2 and 6. She's also not feeding well during the day - popping on and off to look around.
She's ebf btw. Does this sound normal?

yes it sounds normal.

Now is a common time for reverse cycling, growth spurts and developmental spurts (meaning crapper sleep). Reverse cycling can creep in as they suddenly notice there is a world around them they want to look at it, so save proper feeding for when it's dark. You can try feeding in quieter places or a darkened room.

The 4 month sleep regression can last until 6 months btw

Yep. They go all over the place with feeding frequency. All the growth spurts, sleep regressions, and even changes in weather.

We had this and I found feeding when he was sleepy, either before or after naps, helped him take more during the day.

Gngh ! I'd like to try to avoid the darkened room thing, sounds a bit of a nightmare and have a ds aged 3 so can't keep disappearing off to a darkened room. Have been feeding more frequently the last few days but just seems to make her windy so looks like we're stuck with the two am thing. Just a bit disappointing as she had only just stopped waking at two and going for a bit longer at night. I used to think talk of growth spurts was just an excuse for crap sleepers. Ha! Ds was ff from 8 wks and dropped two am feed at 14 wks.

So looks like DD is going to teach me a thing or two!
