Haha I dont have a middle child but they're all painful sometimes in their own ways. Ds #3 is my most stubborn, just like his dad. Was such a placid kid up until he turned 4 then BAM! We butt heads every single day atm. Lucky baby 4 was already born when he turned 4 otherwise I may have given up lol W is such a placid kid, quiet and easy going (except for when he is bossing his brothers around) so I got lucky there!
