Sarah Pattison, from Roydon, found out she was pregnant within 20 hours of joining her local Slimming World group.

But after being reassured it was safe to continue slimming when she gave birth just over seven months later she was still 3lb lighter than when she joined. And by the time her new son, Hugo, was 10 weeks she had reached her dream target weight having lost two and a half stone.

She said: 'I'd gained about one stone after each of my previous pregnancies and I was adamant that I wasn't going to gain a third stone.'

She embarked on her slimming drive after a holiday. 'When we went on holiday last year I needed to buy new clothes, in a larger size, because things didn't fit anymore,' she said. 'I then saw a photo of myself which horrified me and I decided I had to do something about it.'

Roydon Slimming World group co-ordinator Natalie Duke said there was a specific plan to help expectant mums manage their weight throughout pregnancy.

She said: 'Hugo accompanies Sarah to group now and everyone loves him. He's as good as gold and he has inherited lots of surrogate aunties and uncles!'
