Feeling twins move?

I will be 27 weeks pregnant tomorrow with twin boys, I’m just wondering if at this point you could determine which twin was which?

I have a anterior placenta and a lateral, I can’t feel the twin with the anterior or at least I don’t think I can. Im struggling to tell them apart.

At what point do they become regular with movements? Some days I feel it more than others.

Any advise appreciated.

One concerned mama here ❤️❤️❤️
