I need a little help here.

Nina used to sleep through the night at 6 weeks. Now at almost 10 weeks, she is waking around 4 times a night. One of those times she has a feed, the other times I have no idea why She isn't hungry, she has a clean nappy & she's warm & snug.
Every night it starts around 3am through to about 4.30am, then she sleeps till about 5.30, this is when the day starts!
Each night I do the same thing with her at the same time to try & create a routine.
She's not a very good sleeper during the day also. I've tried rocking her to sleep, putting her in the bouncer, in her cot, in the car & even the pram. She'll sleep for about 10 minutes, then is wide awake again.
I can see the tired signs straight away and this is when I try to put her down for a nap or for bed, but it doesn't work.

I was initially thinking it may be a growth spurt as she has put on 350g in the past week, but not sure. She did have her needles last Friday and is still sooky from that.
