i gave it in fromage frais from about 8 mths and by its self at about 1yr. Ds loves them so eats them most days at the min. To be honest i didnt think about reaction so maybe just try him with a small bit of one u eat and see if anything happens??????????
strawberry is a great practice food to help your ds use a fork. my ds loved strawberries and i cut them up into half chunks so he could easily poke his fork into them and put them in his mouth. he found the strawberries so tasty, he made the extra effort to use the fork.
Have been givng DS mashed up strawbs since he was about 7mths. I mix it with plain yoghurt for a snack or with his oatmeal and he loves it. I did start him with only a little bit to see if there was a reaction and he was absolutely fine.
