Since getting back into LBT, I couldn't help but wonder just how old Littlefoot and his friends are. This is what I came up with in terms of their ages:
Littlefoot: 8
Cera: 8
Ducky: 8
Petrie: He always seemed a bit younger than the others(Spike aside) so I'd say 7
Spike: 5
Chomper: 4
Ruby: Can't really say since not alot is known about her
Littlefoot, Cera and Ducky seem more knowledgeable than the others. It's difficult to say just how old Petrie might be since we never saw him hatch. However given his way of speaking and how he depends most often on Littlefoot or Ducky(Sometimes Cera), it's safe to say he's most likely younger than they are. Now considering that by the time of both Land Before Time 5 and the TV series, Chomper has without a doubt gotten older(Spikes on his tail, ability to speak, small muscles in his chest).
However this is just my guess on their ages. How old do you guys think they might be?
