If there is any kind allergy running in the family and especially if its food related then you should first ask the doctor before introducing anything into the diet of your bundle of joy.

Allergies to nuts, nut products and some seeds may only affect one per cent of the population, but for those who are at high risk (people with allergies such as hay fever, asthma and eczema in the family) it's best to steer clear of them altogether.
Other foods to avoid giving your baby are:
Salt - babies can't cope with more salt than that which is naturally found in foods.
Sugar - encouraging a sweet tooth can lead to tooth decay. Add formula or breast milk to sweeten up your baby's food if necessary.
Honey - contains similar properties to sugar and will cause tooth decay. You shouldn't give honey to your child until he's at least one year old, as it occasionally contains spores which can cause very serious illness.
Nuts - whole nuts should not be given to any children under five years of age in case they choke on them.
