Just wondered what others think about this.
My local children's centre run a toddler drop in group. They are supposedly nut free. The snacks (e.g. bread sticks, biscuits) they have for the kids are often labelled "not suitable for nut allergy sufferers due to manufacturing labels". One of the workers told me she had nearly put almond essence in the playdoh to make it smell nice but had changed her mind on a whim. Obviously I check everything anyway because my dd is still young so I just don't allow her to have the snacks and so there has not been a problem (at least for me).
