I think that this expression " hatırlayanlara" means " to remember of something, someone or some situation, as well I am B2 level of Turkish and I can translate some for You, so: The traduction is that " All big men once their child (though it is rare to remember them either)" and, "hatırlamak" is to remember but " Yanlara" means side / beside. So, the complete meaning is that when we are big guys or ladyes and we grow up with ages, etc, we must to remember all of our child time. And when we look for each child we " remember" this time as they living and we compare with "besides"*/by side of them. Other meaning is to remember when we were as a child and compare how the time passed! I hope I helped You some! Best Regards.

Hatırlayan means : A person who remembers Hatırlayanlar means : People who remember This sentence can be translated like that : Though ,It is hard to come across someones among them who are remember this.
