What should I do?

Soo I have highlights at the moment and I’m also expecting our second baby on FEB we have a 15 MO old as well. I had mentioned to my SO that I wasn’t so sure how I would manage to get my hair retouched every certain month with a new born + toddler + giving out birth. It was easier for me with my first but now thinking about going to the salon with two babies it’s guna be a little harder especially in the first few months. Considering blonde is a color you need to retouch every month or so. I told my SO I was thinking of going brown for awhile until our second baby is a couple of months old I feel it will be easier for me and everyone he said whatever you want baby. Or I told him if I go and touch up my roots I won’t be able to get my hair done again until my baby is a couple months old and until I feel like I’m ready to be out with two kids. Don’t know what to do. 🤨😫
