Growth spurt??

[FTM2022x]

My baby is 6 and a half weeks. For the past few weeks she’s been sleeping 6-7 hours at a time overnight but the past 2 days has gone back to waking every 3-4hrs for a bottle. She’s also more fussy during the evenings than she was. Does this sound like a growth spurt? How long do they last?

Could be. At that age growth spurts usually last just a few days. Although I swear my boy was permanently on a growth spurt.
