CareAnn I think you could do very well with this.
Lots of successful bloggerss basically chronicle their day and you can do the same.
for every stage of the child's development there's going to a pile of stuff on amazon.
There's lots of stuff on allergies too - low allergy bedding, air filters
Mountains of material on health - yours and the child.
I'd say do some brain storming - search on Lynns blog for help on that and keyword research. And if you have not joined the Elite group yet do so and get extra help.
And get into a habit of blogging daily as soon as you can.
Are you on twitter? That could be a simple place to start.
Twitter is blogging with 140 characters at time. It's easy and fun
All The Best
