Whilst there is no specific period to wean your child from a feeding bottle, we would recommend introducing the straw cup from 9 months of age. Introducing a straw cup at this age may assist in preventing tooth decay and is the first step towards teaching your child how to sip and eventually drink from a normal cup.
As every baby feeds differently, do feel free to drop us an email at customerservice@hegen.us should you require more assistance on this.
