Wooden, Silicone or Plastic Toys

Hello mga momshies! Ask ko lang which is better pag dating sa toys? if yung wooden, plastic or silicone. I'm planning to buy toy like rainbow tower yet i'm undecided kung ano klase nung toy. Gusto ko sana nung wood kaya lang baka naman sobrang tigas nya masaktan si lo habang nagpplay. any suggestions po. thanks
