hi my name is carrie n im 18. i remember i didnt stop drinking out of my bottle untill i was 4 years old. im not sure if i remember if it was the smell or the taste …prolly both. i do remember how embarassing it was i had to go into another room when i was outside of my home b/c i was worried of kids making fun of me. then i switched to a sippy cup with a lid untill i was prolly 10 or 11 now i just drink from a cup but i will not drink without a straw it to gross! so now reading other peoples stories i dont feel like such a loser now! its just normal for cool PKU people like us!
