Lol make your question clearer because on ice age 3 Peaches is the little daughter of Manny and his wife :) and she was born at the last of the ice age 3 movie :) she is a girl also and by the way she will be in the ice age 4 movie also.
No, the official title is Ice Age: Continental Drift
It depends when this question was made. The current ice age movie is number 4.
No one really knows if Ice Age 4 will come out, or if Animated Dreamworks is creating a Ice Age 4 movie. Just wait for maybe a year, and if the movie does not come out, well then there is no Ice Age 4.
Steve Martino, was the director of Ice Age 4 Continental Drift
Please clarify you question. The baby that appears in the first Ice Age movie will not appear in Ice Age 4.

Since i don't know which one you mean, I will give you all of the ice age movies. 1. Ice age 2. Ice age 2 The Meltdown 3. Ice age 3, Dawn of the Dinosaurs 4. Ice age 4, continental Drift Hope this helps!
No. On December 20, 2013, 20th Century Fox has scheduled Ice Age 5 for July 15, 2016
It depends on your opinion. In MY opinion, Ice Age 4 Continental Drift was 1,000 times better than Brave
She plays as Steffie the wooly mammoth. 
well i didn't still think that they might bring another ice age movie but i think as they made ice age 3 quickly they might bring ice age 4
