How Long your LO use a milk bottle for?

I change it every 3-6 months, because it can get invisible hairline cracks and microplastics/chemicals will start leaking out after - generally I change once the markings start to fade! As a whole, my LO is 25 months old and still using milk bottles :)

mine is 15 mo and he is still using a bottle but he has sippy cups too!

Depends on how it is being cleaned... Change every 6m if possible

It’s advisable to change every 6 months or so...

I only change when the bottles start turning yellow.

i only change once it turns yellowish

i use it for 6months then i change!

6 months and change

Till a year.

6-7 months.
