Three-year-old Caiyro Gould may not understand that his little sister, two-year-old Bella, has Down Syndrome. What he does know, however, is how to be a big brother to her and acts accordingly by taking care of her and being protective of her.

Jess Gould, 33, is rightly proud of the special bond that her children have developed and documented the pair’s beautiful relationship through photos that have won lots of fans on Instagram.

Jess, from Derby, said: “There are only 13 months between them so they are really close, they love playing and spending time together.

“I am so happy knowing Bella will always have her big brother to look after her.

“We all use Makaton, a form of sign language and he picks that up and he is signing with us.

“Caiyro says regularly that he loves his sister- they squabble but they also show a lot of love and affection to each other.

“He doesn’t know any different, Bella is his little sister and that’s all he knows-he plays with her and looks after her but he’s only three so he doesn’t really understand a lot.

“They play games together and he likes to help her walk by holding her hand or if she gets upset he will give her her dummy.

“I am very proud of them both, I will always worry about both of them growing up but it does put me at ease a little that Caiyro won’t be too far away as he’s only one year older than her, meaning so he can tell me if there’s anything I need to know regarding school.”

The part-time administrator admits that her initial reaction when she was pregnant was negative by she hopes she can serve as a positive example for other parents who might find themselves in a similar situation.

She added: “I think because it wasn’t what I was expecting- the only way I can describe it is like when you go to an ice-cream shop and you want strawberry but they don’t have it so you have to have something else- it still tastes good, it’s not the end of the world.

“Everybody who meets her love her, they can’t help it, she is that kind of child.

“The minute I heard Down syndrome it was straight away a bad thing and I don’t want it to be seen as a bad thing.

“Bella is absolutely perfect- we as a family, if we could take that out of her we wouldn’t because she wouldn’t be who she is.

“I want people to see that just because you have someone with Down syndrome in your family, it doesn’t stop you from being normal.

“People think that Down syndrome means severely disabled, that they can’t do things.

“We’ve been quite lucky so far, people just love her, she waves at people in the street and they just stop to talk to her.

“I know that we are going to have some negative interactions in the future and I’m fully prepared for that.”
