A bereft toddler spent more than 24 hours cuddling his mum's body inside their family car after she died at the wheel.
Alina Roberts, 33, suddenly died while driving two-year-old son Benjamin home from a day out at a local children's farm.
The primary school teacher was 22 weeks pregnant and had only married her husband Alex nine months earlier.
He raised the alarm when the mum and son failed to return home to Long Eaton, Derbyshire, from their trip.
Police eventually found Alina dead behind the wheel of her car with Benjamin cuddling her in a street in Long Eaton, Nottingham, more than 24 hours later.
Detectives have ruled out suicide or any suspicious circumstances and a coroner is now investigating how she suddenly died.
Alex - who buried his wife last Saturday –told his local paper: "I was supposed to go with them but at the last moment I said I would stay and do some tidying up.
"We had a kiss and a cuddle when they left.
"After about an hour I sent her a message asking if they were having fun.
"It's devastating to know she won't be able to see Benjamin growing up and what should have been our bigger family.
"I will miss living our lives together and sharing those experiences with her."
Alina had taken Benjamin to the popular Lanes Farm in Breaston, Derbyshire.
Alex said: "After about an hour, I sent her a message asking if they were having fun. It was about 3.30pm when she replied to say she was coming back in 10 minutes.
"After a while, I tried phoning her but it went straight to answer phone. Eventually, I went out in the car and drove the route I thought she would have taken but I couldn't find her.
Alex added: "Benjamin is fine but he was obviously scared and frightened. He had been in the car all that time."
Describing his wife, Alex said: "She was a very kind, loving and caring person and a very loyal friend.
"Family was very important to her and motherhood came naturally. She had a very special relationship with Benjamin, which I will always remind him of."
