Para po sa akin, yung "Jumper chair" is not recommended, similar to a walker, sa halip na makatulong ay it might delay pa the natural development ni baby sa paglalakad. I also wouldn't recommend the "push walker", kasi kung hindi pa talaga kaya maglakad ni baby, baka madisgrasya lang kapag nilagay nya weight nya at may gulong/ magmove yung walker. Good thing ay baka maentertain sya sa mga toys attached to it but I wouldn't recommend using the walker itself. ...just my opinion...
