How are you guys cleaning baby's tongue? I find it so hard to clean my boy's tongue that is covered in milk. I tried a wash cloth with warm water but all he does is laugh and move is tongue everywhere so I can't reach it lol any tips?? I don't want any build up to cause thrush or anything like that
