thankfully though with only her last born daughter and not my hubby..Phew!She breastfed her till she was like 5 or 6 years old. And I can say with surety that,at least in their case, this "extreme parenting" certainly has many mental long term side effects for both mother and child.
Mind you this is not uncommon as we think *shudders*
Personally I go with the Islamic principal of up to two years only, though of course for many mothers,even stay at home ones, it rarely lasts that long. And shame on anyone who equates being a good mother to the time you spend nursing your children. Whilst mothers milk is most beneficial and healthy for infants, not everyone can do it.
