Sensitive to smell

Mummy: For the past 1 month, Chloe has been very sensitive to smell. Whenever I go to public toilets and she wants to follow me, once she step into the cubicle she will give me those "want to vomit" look. And today, the toilet smell was still bearable, but perhaps she's shorter and get to smell more from the toilet bowl, she vomit out the yakult she had 10mins ago and the chicken rice she took 2hrs ago. Her top, socks and shoes were stained with yakult (but strangely her 3/4 pants were not stained at all). Hubby suggest going home to change her clothings and shoes instead of buying new ones, to save money :P
