Jennifer, who is married to boxer Robbie Tickle, recently spoke to us about suffering from post-natal depression after Bobby's birth three years ago.
She told us: "With Bobby I had normal baby blues, but they just didn't go away. My mum spotted the signs of PND as she had also suffered with it. I went to my GP and was diagnosed with post natal depression. It was a tough time, but we got through as a family. I had anti-depressants for six months and recovered.
"It was at the forefront of my mind during my pregnancy with Harry. But I knew what to look out for, and so did my family. I did feel weepy for the first few days, but it all went away. It was a different story this time around.
"There's a stigma attached to PND and mental health, and there shouldn't be. It's so important to talk about it. Tell your family, talk to your doctor. Support is hugely important."
