The products are all certified for their age use. We offer a note of caution : Many suppliers offer infant – toddler materials that are CE certified 3+. Their website information says 0, 1 or 2 years, however the box will clearly have a CE 3+ – not suitable for children under 3 declaration or no CE age. This we will not do. The products in this section are CE certified for use at the age specified and this is on the box. The 22 BioBuddi Educational products which are 18 mths plus are not included here to avoid repetition.
