Sucking thumb

Pigeon or just dry cloth will do. Exposing them to germ can be helpful in developing their immunity (but not in places like hospital and clinics)

Wet-wipes that are anti-bacterial and children safe. I’m using Peekaboo and Cloversoft.

Pigeon anti-bacterial wet wipes or Cloversoft anti-bacterial wet wipes are good

I'm using lec and pigeon hand and mouth wipes.

Can try using Pigeon anti bacterial wipes
