Infants delight in having an impact ...

[smartenglish]

I would like to know the difference in meaning between "1" and "2"?
1. Infants delight in having an impact and in creating change.
2. Infants delight in having an impact, in creating change.

Re: and comma

Sentence one is about doing two things separately.

Sentence two is about doing/achieving two things together.
