help in finishing 2 commands

the first one:
i am trying to build a command that searches a text file
and outputs the number of words which consists of two 'b' characters
in each word separatly


(the b characters must be separated from one another)
i tried to use grep [b][b] filepath
then i know that we need to use pipe to count the result

but it prints all the word with the two b chars
one next to the other

i tried also
fmt -1 file-name | grep '^[^b]+b\{1\}[^b]+b\{1\}[^b]+$' path

didnt work either

the second one is:
i tried to build a command to replaces the word "include" with

in each *.h type of file in a certain directory
and to display the lines in which the switch happened.

i did a command and i dont know why its not working

find /usr -name "*.h" -exec sed 's/include/exclude/g' {} \; |grep exclude

if you know Perl, try this:
while (<>) {
    print if (m/b[^\s]+b/);

run it as:
perl file
