My bub was a prem, so in the begining I did not let anyone hold her before their hands was not washed, I sterilized EVERYTHING and I kept her away from sick ppl and public places. As she grew, I started to relax more and more. I stopped sterilizing her bottles when she started crawling. I just figured that the germs on the floor is worse than what could be left after hot, soapy water. and BB helped me realize that!!
At the moment she puts EVERYTHING in her mouth - other ppl's fingers, carkeys, shoes, trash (if she gets to the bin before me)
The one thing I am still very tatty about is pets. When and if she catch the cat, I will wipe her hands and I do not let the dog lick her or let she lick the dog. That is still a no-go zone for me.
