Twins Jake and Chloe Ford were found dead on December 27 2018.
They were discovered after Samantha Ford had a collision with a lorry at 2:50am and told rescuers to check her home because her babies were there. Pathologists believe they died the day before.
Their devastated father has since posted tributes to social media in which he talks of his loss. In one he wrote:
'My children were everything to me. They were my world... I made a promise to Jake and Chloe that I'll be the best man that I can be. It starts today. Jake and Chloe forever xx'
In court, prosecutors asked for a court hearing to be held on June 10 at which the Crown could confirm if her guilty pleas could be accepted. Samantha Ford will be remanded in custody until then.
