Query: not for a toddler who drool constantly

When the product states that it's waterproof, I expected my son's shirt to stay dry at least 1-2 hrs. but it was very disappointing to find out within 30 min. his shirt got wet. even though it has plastic layer in the middle, didn't feel like it. it wasn't absorbent at all.according to the packaging, it's for 3 to 12mo olds. amazon's product description doesn't say anything about suggested age range. my son is 16months old who drools constantly. maybe this product should only be used for kids under 12mo. and doesn't really work for heavy drooling toddlers. very disappointed in the product and amazon lacking product description.
