Agree that it was slow to load.
I think that your basic problem is that it is - as the name suggests - just another mummyblog. There are so many out there already, with a great following, superb design and contacts to PR companies.
There is nothing on your blog that differentiates from the thousands of similar mummyblogs out there, and the Tumblr design is a bit clunky. (I am not a fan of tumblr tbh).
I also think you have to mix up your posts more, as the first few are all adverts.
Sorry to be so discouraging, but I don't think that there is a lot of money to be made in blogging unless you are willing to put in a lot of time and effort to make your blog different from all the others.
