with DS it was ages, about 12 weeks or longer ( poor BHL ) but I did have a tere so it HURT and HURT alot...

DD1 I think it was about 3 weeks...

DD2 I cant remember but it would have to be before 4 weeks, but that was only because BHL was going to be away for 6mths so if it wasnt then it would have been a very long time
