6month baby constantly having disturbed sleep

[TruffleTasha]

Hi, my little Girl, has been having disturbed sleep for the last four weeks. She never used to, she used to sleep all the way through, now something is making her wake up several times in the night. Some nights she goes all the way through, I have no idea what is causing this? I did start to wean her about one month ago, wondering if this is or maybe something elsr, any ideas and/or suggestions
Thanks x

Teeth??

She's a baby.
That's definitely it.

You can work through all of the things it might be. You might hit the nail on the head first time. You might try everything and nothing works.

This too shall pass. Etc etc.
Quite quite normal.
