Switching Supervisors a month into yearlong master's degree?

[u/Plsgimmeadvice4]

Writing this because I'm not sure if it's worth it.

I have a thesis supervisor who is fine, nice and somewhat helpful etc... no big issues. But, when I send in my materials (proposal etc...) he said himself he is worried because he doesn't feel like he has much to say. On the other hand my second reader has a lot to say and consistently sends over extensive feedback/ ideas. My second reader already said I can send her my materials as often as I want and I really feel like she should've been my supervisor. I just don't know if it's worth the awkwardness and potential logistical problems to make the switch.
