recently i watch Japan drama miracle man, and it's quite nice drama. I search some drama with maybe have the same plot as this

i love when they include child actor in the drama too   so the male lead is not really smart, but then he like the girls and try to do the best for her ... 

it really make me tear up especially the child have some disability, i like how the male lead is never give up and trying to do the best for her

another drama that have similar plot is Korea drama birth secret so the male lead is not smart, 

he love the female lead and want to do his best for her  they have children too,

so maybe you guys have some recomendation like drama above 

- the male lead not smart,but love the female  

- there is child actor/actress

- in miracle man, the child have some disability 

- in birth secret, the female lead have amnesia

Thank you

Autumn's Concerto ---> Male lead gets amnesia. There's a child actor.
Beautiful Life ---> female lead has a disability.
Definitely will make you cry,

1 litre of tears - feamale lead has a disease
Marriage contract - female lead has a disease and she has a daugther (lovely child actor)
Koizora
Ohh and also...Boku no Ita Jikan Male lead has a disease
You can try:

Daisuki (J-Drama)

Marumo no Okite (J-Drama)

Both are heartwarming family dramas which have kids. Miracle Man was a nice drama but I like these two much more :)
Uncontrollably Fond and Fantastic are both kdramas that feature leads with terminal illnesses!! I liked both a lot but they're both very different from each other!
Koizora
Wonderful Life (but happens towards the end) - oldie but a goodie.
Super daddy Yeol (similar idea to Marriage Contract)

Dramas:
Good doctor, this has lots of children, male lead is disabled
Secret, it had a kid in the first half which is the reason why I cried lol
God's Gift - 14 Days OMG THIS ONE I CRIED LIKE A BABY, it's about a mom trying to save her little daughter

Movies (if ur interested):
Ai wa Mieru, married couple that both are blind
Miracle in Cell No. 7, didn't tear up but this one's about a kid that has a dad who's disabled, but it's very sad
The Crucible, very tragic too, about a school of deaf kids
