I don't know if it is normal, but I wouldn't think it is uncommon. With Former T I used to very much look forward to my next session with her, whether it had been one week or three. With current T, I can take it or leave it. I think it's good that you want to see your T though because from other posts it sounds like you've been making good progress and that you two are a good fit! I think it is natural to want to see someone who is helping you.
