The 47 year old welcomed the newborn with her ex husband, former Hollyoaks star, Jamie Lomas on 11 February 2009. However, Archie arrived 18 weeks early, and sadly died just moments after he was born.
She accompanied the emotional image with: "15 years since life changed forever. 15 years of missing you, of loving you, of wishing we could hold you again. Of wishing we could hear your laugh for the first time. Wishing we had heard your voice. Wishing we had got to see you play and run and enjoy your birthdays, as you so deserved to do.Kym then expressed how she plans to "celebrate" her son, and the "beautiful boy," that he was.
"I know you will cuddle him right back for us," she penned, before adding that it's "comforting" to know that they will be together. Kym concluded the emotional post with: "Happy birthday son. We love you always and forever. Kiss Grandad from us."
