I am a sucker of slice of life anime specially with centric themes which include a emotional depth in series and gakuen babysitters fits the spot perfectly . The whole story is about a schooling boy who is pretty good in taking care of babies . Through story telling you can tell that author has a very good understanding of toddlers and young kids. This anime manages to be charming and cute yet at the same time includes some genuine drama and moments of shyness .
This anime had amazing voice actors, great animation, great life lessons. The storytelling was not fast paced they just showed us wholesome moments and quality content in their life with a very subtle life story in the background. The atmosphere was always heartwarming, got some great characters, this is a happy anime. People usually love shows which tackle real life struggles and gakuen did same , attracted a fair audience .
Not sure why it's rated low , in my opinion it's deserves more .
