When Dia first heard that Chika and Riko were having a baby her first thought was "oh god, the idiot is going to have a child". She was happily surprised when Chika turns out to be an incredible mom who dotes on her bab always and somehow frets more than Riko does when she ends up leaving her with someone else. It's that part that really convinces Dia that Chika is a good mom.
Dia is like Maleficent in the background making sure the baby doesn’t get hurt or anything. Riko DOES wonder why their baby’s first words are “buu buu desuwa”
