My wife and I are are starting to wean our 5-months old baby girl. What we are trying to do is a kind of baby-led weaning in which we basically give her the same things we are eating at our meal, in spoonfuls small enough such that she can swallow them without chocking. She seems to appreciate them, she reacts positively to the spoon, she opens her mouth, sometimes she even "throws" herself towards the spoon. She is not yet able to properly swallow, so a good part of what we give her falls down from her mouth, but I guess that's part of the learning process. Because of that, what she actually eats is rather small, so then she has her usual breastfeeding after her meal with us.
For the moment (a few days, right now) we haven't given much thought at what we would give her, except being attentive that she would like it (and, for the moment, she seemed to like whatever we would propose her). However, we are now asking ourselves whether there is any last-longing damage prematurely introducing some food might cause.
For example, could it happen that prematurely introducing some kind of foods, even if she likes it, might produce allergies or intolerances or coeliac disease?
Notice that I am not asking if food might trigger reactions to allergies or intolerances she would already have (or develop in the future) anyway, but only if that might bring to an allergy that would not have come if we didn't give her such food.
