If you liked Kemono no Souja Erin | ...then you might like Sayonara no Asa ni Yakusoku no Hana wo Kazarou |
Both anime deal with the relationship between mother and child and how those bonds define a person's character. There is also the age progression factor, in Kemono no Souja you see the main character growing up and developing as the show progresses. On other notes, good animation and a pretty nice OST
