por estar pendiente de mí
Espero que se encuentre bien de salud.
Le agradezco por el apoyo y gracias por estar pendiente de mí. Recibí su regalo, estaba bien bonito.
Pensaba dejarla como "... thank you for staying alert..." pero como que si no encaja en el contexto y la situación.
Alguna sugerencia.
Non-PRO (1): AllegroTrans
When entering new questions, KudoZ askers are given an opportunity* to classify the difficulty of their questions as 'easy' or 'pro'. If you feel a question marked 'easy' should actually be marked 'pro', and if you have earned more than 20 KudoZ points, you can click the "Vote PRO" button to recommend that change.
How to tell the difference between "easy" and "pro" questions:
An easy question is one that any bilingual person would be able to answer correctly. (Or in the case of monolingual questions, an easy question is one that any native speaker of the language would be able to answer correctly.)
A pro question is anything else... in other words, any question that requires knowledge or skills that are specialized (even slightly).
Another way to think of the difficulty levels is this: an easy question is one that deals with everyday conversation. A pro question is anything else.
When deciding between easy and pro, err on the side of pro. Most questions will be pro.
* Note: non-member askers are not given the option of entering 'pro' questions; the only way for their questions to be classified as 'pro' is for a ProZ.com member or members to re-classify it.

for caring about me / for caring for me
And so I would read it as thank you for caring for me (and I would probably choose caring for me in this particular case instead of caring about me, precisely to allow for something more than just "thinking" on the reader's side although I feel caring about sounds just a little bit more accurate and natural within the context).
I am grateful for/appreciate your support; thank you for caring about/for me.

we can be flexible here as it's about how a child would word it
