The gemara in Sukkah 42b says that once a child reaches an age when he can eat grain, "marchikin mitzo'aso umimei raglav."<br><br>I understand that qualitatively, there is a difference between the tzoah of a baby and that of an adult. I have two metzius questions:<br>
<br>1) When does that change actually take place? Is it actually eating grains that affects the change, or is it solid food in general?<br><br>2) Is there really a change in mei raglayim? I don't understand why there should be a cutoff age for this, or why the cutoff age should be the same as that of tzoah. (Unless my factual assumption is incorrect, and there is indeed a qualitative difference that takes place at the same time as that of tzoah.)<br>
