Sherrie Bennett has raised money for Alexander Devine Children's Hospice Service, was speaking during Children's Hospice Week.
Alexander Devine is fundraising to build a dedicated children's hospice in Maidenhead, which would take Berkshire children.
Mrs Bennett, who lives in Elizabeth Close, Bracknell, added that a nurse from the Alexander Devine Children's Hospice Service was amazing for her son Declan, who died in 2010, aged four, from a rare blood disease.
"It would be great to have a hospice, it's very much needed," she said. "It would make it more local for families and friends. We didn't have the facility for Declan
but Lucy [Jones] was amazing - the best nurse ever. Before Lucy we were living in hospitals."
Lucy Jones works as a nurse for Alexander Devine, covering east Berkshire while Julie Weston covers west Berkshire.
Lucy looks after about 10 children at present, including Jamie Turvey, four, from Binfield, who was named Child of Courage at the Pride of Bracknell Awards last Friday. She said: "For the children with life-threatening or life-limiting illnesses living in east Berkshire, a local children's hospice would be vital as travelling long distances is not easy for these families. Also, when a child is very unwell the whole extended family wants to be near by and travelling across counties is not supportive.
"A children's hospice can provide 24 hour hands on support which may be exactly what a family needs, however, the most frequent reply I get back from parents is 'that's too far to go, isn't there one in Berkshire?'."
Alexander Devine is asking youngsters to design an A5-size thank you card to be sent out to the charity's supporters. Youngsters pay £1 to enter and the winner will see their card professionally printed, as well as receiving a special gift.
Entries must be completed before noon on Friday, June 7, and sent to Alexander Devine at 113 Whitby Road, Slough SL1 3DR with a cheque.
