See Caroline, there is nothing wrong with your pregnancy brain - you champ!!! I will find out what she uses and then have a go at it. It may as you say need just a little lemon juice or vinegar. I want to find out what she uses anyway and research making it as another option to present to her
ROFL - gosh I don't think mine is back to normal YET and DD is 2 1/2 !! - my kids keep trying to work out how much brain I have left if you "apparently" lose half of it with each pregnancy - now that is scary
In my experience, what little brain you regain after birth is totally destroyed by teenagers!!
