Creative professions require tranquility and concentration, so you have to create a favorable environment in the house for normal humans. No matter where your husband arranged - at the dinner table or in the office. The main thing that it was convenient, and you at this time is better just forget about his presence. Quietly about their business. Suppress the urge to talk and do not distract him with questions about anything.
In any job, regardless of whether it happens in the office or home computer are "ups and downs". It can be obtained quickly or, conversely, bad move. Man it's frustrating, only one - experiencing the failures quiet, and the other at this time tearing your hair out. If you see that something similar is happening with your husband, do not climb under his hand, give him the opportunity to deal with their difficulties. If he needs your help, you will always be able to support it.
In the event that your apartment is small and her husband do not have a stand-alone desktop space, try to be quiet, and teach your children to this. It is clear that no sane child can not a day to be quiet, so try to come to terms with her husband in advance of when a child can run around and make some noise, and even better if their games and entertainment will be together.
In a situation where both of you are working from home, you should agree in advance not to interfere with each other, and household responsibilities can be played either by one or together. If you go to work for the day and we are confident that the husband is obliged to prepare for the arrival of your dinner, talk to him about it. If he knows how to cook, you will likely be able to do it without any problems.
This also applies to household duties. Negotiate everything at once, so that in future there were no recriminations about not nailed down or repaired cistern. By the way, if your husband - a good professional in his work and earns a lot of money, but nothing about tanks or nails, it makes sense to invite experts to repair, not "stretch" your other half. In any case, you should always clearly spell out what you expect from each other.
