@Lady Vee - I weaned my daughter at 4 months and it was the right thing for her. I just tried my daughter with really pureed verions of what we were eating and she loved it, u could tell, the different textures etc.

I think u have to look at your child and decide. Its World Health Organisation guidelines that suggest six months. I think four to six months is okay. Plus if your other two were weaned at four months and are healthy then u really have to do what seems right.
