Why isn't my baby sleeping?

[Annalogy]

My 6 week old has decided to be wide awake, despite being up since 6am with only a 30 minute nap all day

She's been having 3oz every couple of hours, when she is usually every 3-4 hours.

Has anyone else had this before? I'm knackered

So tough! I feel for you. Possibly growth spurt - common at 6 weeks - and now probably overtired and can’t wind down. Can you hold / rock her to sleep? Does that ever work for her? I have 3 young kids and remember this sort of thing so vividly!!! Good luck xxx
