In the rebooted series of "Rugrats," Susie Carmichael's age has been decreased to 2 years old, making her the same age as Chuckie instead of being the same age as Angelica as in the original series. This change has also affected her friendships, as she is now part of the regular group of babies. The reboot has made Susie a more integral part of the main cast, and she is no longer able to talk to the adults. This change in age and communication ability has likely impacted her interactions with the other characters. For more details, you can refer to the Nickelodeon Wiki here and the Rugrats Wiki here.
