We are not aware of any ceremony in Islam which is called Bismillaah Ceremony for children. Therefore, you should avoid such a ceremony so that one will not fall into innovations.
There are no obligatory celebrations in Islam, whether this is in regard to children or else. We have already issued Fataawa 81275, 88081 and 83120 clarifying some rulings pertaining to a new born child and clarified that it is permissible to make the ‘Aqeeqah as a feast whereby people are invited for a meal.
