Trying to manage it all....my business, the kids, the pets, the house...is difficult. I think that's something everyone deals with. I'm lucky that my husband is and always has been fully supportive of my home business, but I am still responsible for making sure all my mom duties and such are taken care of. Some days it's exhausting. Others, not so bad. I have been doing this for quite a while now so I guess I'm just used to it!
Do what others said, try talking to your husband and explain how important this is to you. Also - having some form or organization helps. On top of that, the best advice I can give is make sure you are making time for your family and yourself...don't get burned out. If you can't enjoy your life and family in the process of working from home it defeats the purpose! Remember to enjoy the little things!
Good luck!
