Introducing solids can always be a bit tricky.
There much mixed advice regarding the age to start solids; it is suggested that no earlier than 4 months but before 6 months. I would say get advice, read credible sources, judge your baby and go with what you feel is right for your family and your child.
ASCIA recommend introducing all of the common allergies IF the child does not have known issues.
However one thing I would recommend that you do, if you are still unsure of what food allergies your child has and are concerned about what your child may react to, is to stage the introduction of the foods.
Give one food then wait 3 days before introducing another. That way it is easier to work out if a food is causing a reaction.
Put it in your dairy or calendar what you foods you are trying and go from there and fingers crossed you won’t even need to refer to it!
The foods that we went with for BRB (listed in order of progress/age) we gave are as follows:-
From four months:
Bellamy’s organic rice cereal
After six months:
Chicken as casserole
Fish as casserole
Lamb as casserole
Beef as casserole
Mashed; Avocado, Mango
Asparagus – finger food
Melons – finger food
Small amount of garlic/onion in casserole
Later on when they can chew it up more we gave bread as a finger food with nuttelex/vege spread/nut butter.

As a precaution I read every single label every single time I purchase it.
I am also not giving any medical advice, I am not equipped to do so, I am merely stating what our experience has been.
