A couple years ago, I took 4 months off training. My biggest fear in returning was my sensei calling me up to uke again. I asked him if I should wear my dogi without hakama so he would not call me up until I got back into the swing of things. He said that wouldn't be necessary and he gave me several weeks to get back into the rhythm before calling me up to uke. Communicating with him was essential, as it took away my fears and let me ease back into Aikido at a comfortable pace.
