This big brother had the most heart-warming reaction to finding out his family are having another baby girl just seven months after his sister tragically passed away.

Grant Stotts could not hide his excitement when the cake he, sister Carly, four, mum Rachel and dad Perry were cutting to reveal his new siblings gender was pink.

As soon as he spotted the colour of the sponge on Friday February 17, the seven-year-old jumps up and down while pumping his fist before high fiving his mum.

Perry believed Grant was hoping for another girl after baby sister Blakely unexpectedly died in her sleep from SIDS back in July 2016.
