My baby

I bore my baby on Apr.12. Now He is now 2 months old, and he is very healthy and handsome. Although he is a little one, he usually smiles and sometimes "talks" with us. But he is easily scared - when he hears some sound, he may cry out loud. Being a mother makes me happy. I love you, baby.

[Good work.  'Yellow-belly' is a very insulting and bad term to use.  I don't think that was the tone you want to use with your baby.  Another, more innocent term is 'fraidy-cat'.]

I think the thing you want to express is "he is a little shy and sensitive" .
