<human>: My so (m, 22) of 3 years and I (f, 21) just moved back in together. We have lived together for 2 of those years and lived separately from last November until a few weeks ago. We have a one year old daughter together and currently, SO stays home with her while I work full time. 

Our daughter absolutely adores him and as far as taking care of her, he does a wonderful job. She is fed, diapered, happy. The problem is the absolute disaster I come home to. Examples: He doesn't wipe off her highchair after feeding her and leaves food crusted to it. Dirty diapers are left on the changing table. Coffee and drinks spilled on the counter will run down the side and congeal there. He does often cook, but makes gigantic messes doing it and does not clean it up.

Today is my day off and I have spent the last four hours cleaning up ants, mopping up mud from his shoes and attempting to conquer the laundry that has piled up in our bedroom. He is outside with his electronic cigarette reading because he needs to relax and it is my day to watch the baby.

I feel completely overwhelmed. I already work full time at a demanding sales job. I feel like I am both responsible for the housekeeping and also putting food on the table. I definitely have higher cleaning standards than he does and I don't want him to feel constantly nagged but I feel like there has to be a better way than we are currently doing things.

How can I get him to help more without being a huge nag?

Can you succinctly summarize the text in 1-3 sentences?
<bot>: My SO is extremely messy and I am not. Working full time and doing most of the housework- how do I get him to help more?
