If your child's asthma is triggered by pollen, there are plenty of steps you can take to make your garden a trigger free zone.
It is best to get rid of the lawn completely and replace it with a concrete, stone or paved patio.
Or you can use wet pour surfacing, similar to that found in some children's playgrounds.
This is more yielding than concrete and can be bought in a range of bright colors, but it is rather expensive.
Bark is another alternative to grass, but it gives off a dust when it breaks down which can also act as an irritant for some children.
There is no need to eliminate flowers, but avoid those that are pollinated by wind borne spores.
Flowers that are pollinated by bees, such as sunflowers, roses and delphiniums, are unlikely to cause an allergic reaction and are often among the showiest flowers.
If you are not sure which types of plant, your local garden center should be able to help.
Mould spores can be a problem outside when the weather is damp, especially in autumn when vegetarian is dying off.
Teach your child to keep away from the compost heap if you have one.
Put up fences rather than hedges to mark boundaries if you can because mould spores collect in hedges.
Peanut butter and crude peanut oil must be eliminated from the diets of children who are allergic to nuts.
Purified peanut oil is safe.
If your child is allergic to peanuts or nuts, ask a dietician for advice on how to avoid them totally, as they are present in a surprising number of processed foods.
When the pollen count is high, consider spending a family day out at the seaside rather than in the country.
