UNHAPPY MOM

I bought a pack of 2 bottles at Babies R Us and I paid R400 for both...a month of having this bottles the numbers started coming off to a point where I cannot see it at all now..I'm using one of my daughter's older bottles where the numbers are still on so I can get the correct measurements...We Pay so much for theses bottles atleast engrave the numbers into the bottles make it worth the money ...I am extremely unhappy 🙁 ...
