How would you do it?

So my husband and I just had our baby boy back in June. He recently lost his job due to this pandemic and got offered a job 12 hours away from us. We've always wanted to have a summer home there and feel its a dream. We also love our house here as its in a prime area and has good acreage to it. He'll be making enough money and some to support both properties and wants our son to grow up in the country like he did. So he proposed that we stay here and come visit him every so often like every month or something. I have a great career here and we are by one of the best school systems so I can see it happening, but we both stop at...what if our son forgets him? Every 4 weeks is a long time for a child and we know we can video chat and all, but I guess how would a three month old understand that? Like he knows his dad's scent, his beard etc. I know there are women out there that have dealt with this....so how did you do it? I'd hate for him to give up a great opportunity but I'm mainly concerned about my son's relationship with his dad.

Let me also say that I don't make enough currently to support both of us with my career unfortunately or I would personally have him stay with me. We would fly out there since he's by a major airport if he were to go. I may not work and go out there, but it would be a little for him to get established...it's a hard decision. Idk I'm at a loss.
