at myself. Welled up a bit (but controlled self) when the mother leaves the baby with the mammoth and then drowns. Then totally lost it at the bit where the mammoth sees cave paintings of his family and remembers playing with the baby mammoth etc before his family was brutally slaughtered ...
... and finally, at the bit when they return the baby to its dad I got all teary again.
DS is thankfully oblivious to my lunacy
