My 13 year old Daughter died from #BrainCancer 4,679 days ago. 💔

I would LOVE to see my Ashley’s name 4,679 times in comments for all the days she’s been missing.

When you lose a Child, the most beautiful word you can hear is their name. ❤️

A Repost & Follow would mean the world to us to keep our Ashley’s story alive.

@AaronGoodman33 I think this is a broad statement. Advanced cancer can mean a lot of things. In general if someone has a short life expectancy of course they don’t need a screening colonoscopy. But this is vague. I do love your posts tho!

@DavidSteensma What about an RBC magnesium level????

I love seeing friends and brilliant educators like @ebtapper teach

My new fav analogy for fibrosis —> splenomegaly —> thrombocytopenia

My 3 year old daughter Lila was recently diagnosed with a VERY rare and aggressive type of #leukemia.

👉 It’s potentially treatment resistant… AND

👉 Requires a bone marrow transplant.

A🧵with all the details we have so far 👇

Please @Twitter help me save my little girl.

Ceci died unexpectedly on Dec 5, 2022 at 14 months old. She was our daughter & we are devastated. She was so smart, smiley, stubborn & squishy. She adored the rabbits in our yard & playing with her nanny “Shang NaiNai” & sisters. She is loved & missed beyond comprehension (1/5).
