Hello, Welcome to DogChihuahuas.

,
The pictures are adorable, and im sure you will be delighted with your new chihuahua.
The subject of children and any dog/puppy in my opinion should be supervised, and monitored, especially with the smaller type, purely because of the danger element of there fragile-ness, i.e being very careful of them falling etc, breaking their little bones, but in all can be thoroughly enjoyed by all.
Keep us posted on your newcomer

Regards
Sarah
