how to avoid Alva baby cloth diapers leaking?

Generally they don't leak.  Sometimes they might leak from the leg, but they don’t leak if you adjust a right size. 

Besides, if the inserts are fully absorbed, they will leak too. 

You do generally have to change them more often than most people change disposables since some leave their children in disposables for 4+ hours. 

You are looking at changing cloth diapers every 1.5-2 hours as a general rule of thumb. 

If you would like some extra absorbency for heavy wetters, try using or adding bamboo or charcoal bamboo inserts.
