So with the help of her 4-year-old granddaughter, Charlotte Coleman, they set to work making a replacement. The new baby Jesus was presented to Rev Bloomfield this week.
"This just makes the nativity all complete. The message is about Jesus. Without the prime star you don't have a message," Mrs Lamberton said.
"It's like having a birthday party and not having the person [whose birthday it is] attend."
She said they had three new wise men who had been acquired from a ward decorating competition and which Mrs Horton had helped make.
"What were the three wise men have been demoted to shepherds."
However, there were only two shepherds so they needed one more for the nativity and Mrs Horton would make a third.
Mrs Horton said she couldn't believe it when she heard baby Jesus had been taken.
She has worked at the hospital for nearly 30 years and knew she had to help.
Mrs Horton got Charlotte to help sew up the new baby Jesus.
"She wanted to help with everything. She is a typical 4-year-old. She loves to learn. She will be a better sewer than her mum.
"It was just lovely to have [the nativity] all together again."
