Daa! Daa! Daa!

how to take care of a baby? well these two anime can definitely help you out. Human baby or alien baby? when it comes to babies, they're a different specie from the adults!  

its exactly like kodocha except thers this cute baby ruu anyway the hcaracters are alike in every way kanata is like akito and miyu is like sana i seriously recomend you watch this 

They both have babies as main characters, but instead of being a Devil baby it's an Alien baby that does a lot of unespected stuff too. The episodes are bigger and the history is also deeper with many secundary characters. Hope you'll enjoy it ;) 

Both are about babies coming fom nowhere and students have to take care of them.They have similar romance and comedy. 

They both have non-human babies that have been placed on earth for some reason. And they both are being rasied by humans with a non-human servent/caretaker. Also both animes have comedy. 

Both have toddler/children and are slice of life animes, however Daa!Daa!Daa! has aliens while Gakuen Babysitters are human based. Both are focused around the theme of "Family". 

It's not about fairies but an alien baby and the main characters LOOKS so much like the ones from Mirmo. In DDD, the two mains takes care of the alien baby and HE'S ADORABLE. just like how in Mirmo, the mains have their own fairies. BUT anyways, it's really cute. The girl in DDD likes a guy too and they're freaking cute! it's a must watch.  

Miyu and Kanata from Daa Daa Daa both remind me of Daichi and Himeko as they are always seen fighting as a way to show their "affections" for each other. Both male main characters in both animes also always teases the female main characters. PLUS there are both cute small kid couples in both anime and not to mention Wanya and Pokota are similar in ways. Both anime includes school life and the joy of hanging out with friends :) 

In both titles, older (Daa! Daa! Daa!) or younger (Sharp) kids are taking care of a baby. This baby came from another world/planet, has supernatural powers and can fly. The daily chores of raising a baby with changing diapers, sleepless nights and other difficulties form an important part of both series. Keeping the powers of the baby in check (especially to prevent it from flying) adds to the challenge. Furthermore, in both titles, some bad guys are repeatedly trying to abduct the baby, which leads to various adventures. Also, there is more (Daa! Daa! Daa!) or less (Sharp) romance. If you want to see the challenges of raising a superbaby, both titles may be for you. read more 

Two young people coming together to take care of a little one whose not their child. Also weird, but cool cat characters in both! 

The plots are really similar, due to irresponsible parents, the female and male lead has to live together. They go to the same school and try to hide the truth from their friends. There are many love interest/ rivals whom tries to stop them becoming closer. The art style is kinda similar too.  

both are about a little alien with superpowers that sometimes causes troubles and both about a teenager girl who have to protect that alien  

thing that makes them similar is the girl moves into the guys house 

Same comedy, with a little fantasy twist! 

in Hanamaru Youchien tsuchida is a sense is taking care of all the little kids and falls in love with a co-worker and in daa daa daa a girl and a boy have no choice but to work together to take care of the little baby. Basically both anime have little kids in it! 

both of them is about taking care of little kids 

Both Slapstick comedy mix with romance ones a about a famous singing idol girl posing as a boy at school the other about two kids trying to take care of a UFO baby. 

Childish Shoujo with the same cute but mildly kitchy feel
