What you should know about childhood allergies
One in 11 children now live with asthma, and with the dramatic rise in allergies that we've seen in the last 20 years parents want as much information as possible to prevent and treat any allergic reactions.
But the lack of specialists, the glut of so-called complimentary therapists and the widespread and frequent publication of conflicting messages on the subject have all made it so confusing to know what to do, where's a mum to start? Dr Hilary Jones has the answers.
Eating nuts during pregnancy
During pregnancy it is no longer recommended that mums-to-be avoids allergenic foods like peanuts or shellfish as there is no evidence that this makes the prospect of allergy in their child more likely.
Breastfeeding if possible for the first four to six months is recommended as the least likely to cause atopy in the child and for developing the baby's immune system.
If breastfeeding isn't possible for any reason, using hydrolysed infant formulas as hypoallergenic substitutes over cow's milk or soy formulas is recommended.
When a solid food is introduced between four and six months it's suggested that less allergenic foods are introduced first, and if there is no reaction then the more allergenic types of food can be introduced shortly after. It's now widely believed that delaying the introduction of foods like peanuts containing products after the first four to 11 months of life can actually increase the risk of food allergy rather than decreasing it.
Dust and smoke
Reducing a baby's exposure to house dust mite and to tobacco smoke remains important for reducing allergy risks in the future.
