Votes were collected for the poll on getwestlondon in the week leading up to the carnival, which drew thousands of entries and created a shortlist of five for each category.
And at Saturday's carnival the judges, including Stephen Pound MP, picked Baby Joseph and Toddler Maisy as the winners.
The adorable pair have now won a full family shoot at the PearceScott Scott Creations Photographic Studio in Hanwell - offering a full family shoot at the studio or park worth £450.
The competition, which drew thousands of votes, was run in association with PearceScott.
One of the competition organisers, Barbara, said: "The Ealing Baby & Toddler Awards annual community event is growing in popularity every year.
"It really is the highlight of my spring, I get to meet a lot of new families in the area as well as having families return year after year as It allows them to have a professional photo shoot of their little one which may not normally not be a priority.
"The online voting is always exciting to watch as it can all change with in minutes I was amazed at the amount of people that voted and shared the poll this year.
"We had a fabulous turn out to watch the final Judging at Hanwell Carnival. The parents of the finalists looked very proud to be up on the bandstand center of Elthorne park."
