My son has just started solids - can we order food for him at a restaurant or is it better to carry purees with us?

It's still better for you to carry puree with you as your son is too young to be eating regular food which has salt and sugar added to them. The oil used is also unknown. I don't and have never carried any puree with me as I feel that when they are below 12 months of age their main diet should be milk hence missing one day of solid should not pose as a problem. That being said my 7 month old daughter enjoys eating together with us. I always have on hand some carrot, celery or cucumber sticks or just some cut cherry tomatoes so she can have something to chew on while we enjoy our meal peacefully.
