Windy baby at night only!

Hi ladies. My daughter is nearly 3 weeks old and is a perfectly settled baby, until around 9pm. As soon as it gets to around that time she is so unsettled and is squirming around. She will do that solidly for around 3 hours (how often she feeds) and then will be perfectly calm again.

She is bottle fed, we use MAM bottles, and she will have colic relief in her bottle (I can't wait til she is old enough to have gripe water that stuff is a god send!!!) And I make sure she is burped for a long time. Basically I just wanted to know if anyone has had similar issues as this? And what you did to resolve it.

No amount of burping, rocking, back rubbing, bicycle legs, bum patting or bouncing seems to work!

I wouldn't be bothered but it's just she seems do restless and unsettled I don't want her to be in pain!

Thanks!
