So glad that you have psosted this, MJ has been going through the same thing on and off for the lst 6 months.
Its really really frustrating and sometimes i feel like i must have done something terribly wrong to make her turn out like this.
Several times DH has asked who the spolit brat is in our house and when is our lovely girl coming back.
I dont know whether giving her options has created this, or allowing her to request things.

I have started saying NO to anything that starts with "i want", this has created a few issues too, but it is slowly getting better... actually thats not true, is she 'wants water, i am not going deny that, so she has to ask nicely before getting it.

Being very pregnant is not helping me either, some days i feel completely intolerant.

Sorry, so no advice, just wanted to share my experience and from the PP, i am guessing that this is totally normal!
