Hi Livvysmum
Thank you for posting on our forum. There may well be parents here that have been through similar situations and I hope they will make contact with you soon. Widowed and Young have lots of groups locally and have a very informal set up. No workers, just people that have lost partners. Another agency that may be able to provide support is Family Lives. They can give support around parenting issues.
• Widowed and Young provide peer to peer support service for men and women under 50 who have lost a partner. It is run by a network of volunteers and offers a range of services. https://www.widowedandyoung.org.uk/
• Family Lives provide general support to families on issues around parenting, emotional support and just generally coping as a parent https://www.familylives.org.uk/ 0808 800 2222
I hope this helps and I wish you well for the future.
Take care, Justine
