My learner´s try. As usual, I´m not quite sure about it, so please wait for confirmation or corrections from other forum members.

I have doubts especially about the first sentence:

• Yazdıklarıma ağırlık vermem lazım - Not sure if this is correct at all?

Anneciğim, sürekli konuşuyorsun, lütfen sus, yazdıklarıma ağırlık vermem lazım. Babacığıma bir mektup yazmak istiyorum. Benim harika babacığıma ne yazabilirim düşünüyorum.
