Manage to get hold of glass bottle from NUK. NUK is a Germany company with longstanding history. I am sure those who are alert would have heard of NUK body powder being withdrawn from market in China.
Back to glass bottle. Plus point for glass bottle of course is: it is safe, does not leach harmful chemical such as BPA. The cons are: glass bottles are generally more expensive and it is breakable especially for older kids. Those who have kids will know that older kids like to throw their bottles once finished their milk. Dont know why. Perhaps they are just experimenting with different things in life. They just want to see what will happen if bottles being threw, they wants to hear the sound of it etc. Anyway, this is kids' behaviour. I think it is universal!!
Will try to find sleeve for glass bottle which can help to minimise breakage.
