is this a growth spurt?

[sleeplessinderbyshire]

Dd is 15sw and ebf. Until last week she fed arojnd every 3hr by day and slept in 5-8hr chunks at night. For the last week it has been max 2hr by day and 3hr at night. She has a bottle of ebm earlier and drank 4oz but then was ravenous 2hr later. Is this the dreaded 4 month growth spurt come early? She is also way harder to settle for naps butseems really well and happy when not sobbing with exhaustion

Yes. Look up the 16wk growth spurt/sleep regression on MN - there are hundreds of threads. It starts at 14-15 weeks as they begin tanking up for it.
