I am a mum of 2 kids. My eldest is and my second is 3 months old. Since my first child I have always relied on and used tommee tippee bottles and never had any issues. However now I noticed on the bottles I bought for my second baby that all the prints have faded so I cannot see the numbers anymore. This makes it so difficult to make formula. I have turned to Dr Browns and have not had an issue no matter how long I soak it the writing is still there. I am very disappointed as I paid alot for these bottles and now I can't use them nor return them. Please do something about your print as it is costing mummies alot of money to buy new bottles.
