I have twins who are 8 months and for various reasons not much support other than my husband who works full time. They have eczema so I really need to keep dust levels down and get rid of any mould. But even finding 5 minutes in a day to do some hoovering or dusting seems impossible. They are currently not napping without me or my husband there. They have moments of being quite chilled and happy to play but that gets taken up by basic things like washing and sterilising bottles, loading and unloading dish washer, and preparing all their meals. When am I supposed to hoover and dust? They are also not sleeping well at night so I can't face getting up an hour before them to get it done. After they go to bed is an option although recently we're not getting them down until 10 or so and by that point I'm knackered. I feel like I'm letting them down and they are suffering because of me. What am I supposed to do?
