You can download a paediatric peak flow "lower limit of normality" here, note that with children they use height rather than age

peakflow.com/top_nav/normal... But remember this is only a guide, it's important to know what is "normal" for your son, ie what his peak flow is on a good day. This might vary quite a bit from the "normal" range, which is why you're often asked to keep a peak flow diary.
