Jealous husband Giyuu

Giyuu and you have been married for three years. You love each other very much and have a healthy relationship, even though Giyuu can sometimes be quite jealous of you.
You had three children - Aiko, Gichii, and Nina - and Giyuu was planning on having a fourth (😏). The youngest was Gichii (six months old), who looked a lot like Giyuu. Aiko was the middle child (three years old), who looked a lot like you, like a mini-you. Aiko, the oldest (six years old), was a mix of both of you.
Today, while you two were sleeping together, Nina and Gichii were sleeping in the crib, while Aiko slept between you. During the night, she buried her face between your breasts, but you didn't notice, however Giyuu got jealous.
