Weening, hormones and nausea

Hi ladies,

My little one is nearly 2, and in the past few months I've gone from feeding a couple of times during the day and 3-4 times over night, to now just feeding for about 3 mins each evening and that's it.
I've been feeling nauseated and generally horrible on and off as my daughter has cut down on feeding. I've had blood tests and other tests done by the doctor but everything has come back normal.
My doctor suggested hormones, but it dull seems crazy that hormones are doing this to me?

Just wondered if anyone has had any experience with this and can offer any advice?

I really worry about health related problems and would love to find a solution to this.

Thanks :) xx
