Yavanna Keogh's 4-year-old son Oscar was diagnosed with Diffuse Intrinsic Pontine Glioma (DIPG), a rare form of a brain tumour in January 2018.
Keogh and her partner Lar were told by doctors that because of the location of the tumour and the proximity of Oscar's nerves to it, it is inoperable and he has a less than 1 percent chance of survival.
According to the GoFundMe set up to deal with medical costs for Oscar, 90 percent of children with a diagnosis like Oscar's have up to 18 months to live.
As Oscar's birthday is June 24, Keogh has requested his birthday be made an extra special one, appealing to anyone and everyone to send him well wishes via a birthday card.
Keogh, who tweets and blogs under the alias MakeUpMonster shared on Twitter: 'Wherever you are in the world - Our amazing son Oscar from Dublin turns 4 on June 24th and he is our world. He has a DIPG terminal brain tumour and this may be his last birthday. IF it’s feasible, could you consider sending him a card to make it the biggest birthday?'

When asked by one follower about which card Oscar would prefer, Keogh added 'Basically any cartoon character that’s on any kids station at the moment! Especially loves Oddbods, Minions, Mickey Mouse, Sesame St, PJ Masks, My Little Pony, Boss Baby, Monsters Inc., all of them'.
