Little Archie had tragically passed away moments after being born 21 weeks and five days too early.
Kym, 44, shared her heartache with friends who weren’t attending the funeral because they felt they couldn’t ‘cope’.
She said on her new BBC Morning Live show: “I had almost gotten to the point where I still didn’t accept anything, but I also found that people didn’t know what to tell me or how to talk to me, so , therefore, avoided this completely.
“Some people didn’t want to come to his funeral because they felt… they just couldn’t cope with the funeral of such a small baby.
“They felt really difficult, it was a difficult thing for them. ”
Kym spoke about her grief to former Gogglebox star and vicar Kate Bottley on the show.
Looking back, the actress initially admitted that she didn’t want to talk about her grief because then “it would be real.”
She added: “When I lost my son Archie 11 years ago now and lost him quite late in my pregnancy…
“Personally, I didn’t want to talk about it at first, because I felt that if I did talk about it, it would be real. “
It was a devastating loss for Kym and her then-husband Jamie Lomas.
Kym has two grown children, David, 25, and Emily, 23, whom she shares with her former partner Dave Cunliffe.
The starlet is also raising nine-year-old daughter Polly with Jamie.
Morning Live is broadcast weekdays from 9.15 a.m. on BBC One.
