Quite right--there is nothing wrong with doing her own functions and taking care of her children--if that is what she wants to do.
I've been reading the Letizia boards for some time now and it never fails to amaze me how so many people just want to gang up on the lady for every minor little thing.
I multi-task--I am married, run my husband's business, go to graduate school, keep house, cook, clean, and I have a little boy with special needs, so I am the queen of multi-tasking. Yes, people do it everyday--but does that mean those of us who do multi-task should criticize someone who doesn't? Actually ,Letizia multi-tasks a great deal I am sure. She performs engagments with her husband, she takes care of the children, has some of her own solo things that she does, etc...
The fact is, Letizia is lucky. She gets to be married the man she loves, spend large amounts of time with her children, and has the respect of her in-laws. Unfortunantly, she does it under the public's eye and they want to criticize her for being a good wife and mother. I suppose in this "modern" age women are often villianized for wanting to raise a family and not have a career of their own. As I see it--Letizia had a successful career, got married, had babies, and now wants to be a successful mother and wife until the children begin attending school. I think it is noble of her and that she should not be criticized for it.
Just my two cents (well, several posts--make it 6 cents!)
