Peanut porridge for 10mth old

Try very small amount in peanut butter form first. Once you've observed a few hours there's no reaction you can slowly increase. My daughter's allergy doctor actually recommends her to eat peanuts regularly to reduce the likelihood to get allergy later on. So if your baby is at low risk group for peanut allergy (if she doesn't have eczema or any other allergy) I'd highly recommend including peanut in her diet as prevention.
