I have a 1 year old and I work from home. My in-laws are coming for a few months and don't help out at all. how should I plan the day now

I think, you can not do enough if they don't help. And your husband too would want his parents to have a good time at your place since they are coming for sometime and will go back. I think, the best you can do is, you give the baby in their lap to take care when you are working. I am sure this much they will do. Else you can tell them that you cannot hold the baby and work in the kitchen or make three meals so during the time you are working, they will have to look after the baby. Also, you can do quick fixes like; make lot of masala on a weekend so that it lasts a week, and whenever you have to make a dal or a vegetable, you just have to add the masala in the boiled dal. Early mornings when the baby is still sleeping, you can prepare lunch that time only, so that you again do not have to spend time in the kitchen. If it is a matter of few months I think you can manage it this way. Else you can keep a help for a few moths for chopping and cutting vegetables and little to do little nothings.
