Sit On It Bean Bag

My son always prefers that the meeting on the armchair pear while eating but I am worried as it could injure his back. I hold it to prevent it from fall but of the this is well for him to sit there?

It doesnt seems different of a videur of baby to me and they sell these in particular for the babies. Provided that it is supported, it should be well - they are a lot more flexible ones than we in any case. My girl liked the armchair pear and appeared very comfortable
