Hello Vasile. This is a very humorous and gentle, loving senryu. I have couple of suggestions: you could change "nearness glasses" to "reading glasses" as that is the usual term in English (for long-sight glasses). It makes it funnier too, as though the Grandpa is reading the infant like a book. Second suggestion: since you say Grandpa (sp), the obvious word might be "grandson" and not "nephew"... alternately, you could say "grand uncle" but this sounds little awkward and long. It doesn't have the casual charm of "grandpa". You could also consider saying "the new-born infant" since "grandpa" implicitly suggests the relationship between them. Anyway, this is not an important point. Despite these minor doubts, this is a wonderful haiku.
