Not all baby bottles sold in New Zealand have accurate markings.
A survey by Consumer Affairs (part of the Ministry of Business, Innovation and Employment) has found that a number of baby bottles sold in New Zealand have incorrect volume markings on them. This means that parents and caregivers could be unintentionally feeding their babies infant formula that is too concentrated.
Check your baby bottles have accurate markings by looking for the standard mark EN14350 on the bottle or packaging. Otherwise take your baby bottles to a pharmacy and ask a staff member to check if your bottles are accurate.
Formula that is too concentrated can cause problems like vomiting, diarrhoea, constipation, and serious dehydration.
