    Rating: 4 out of 5

    everything was good. the only thing is that I didn't get a clear message of what _____ needed the first time. I was truly hoping to do the circumcision earlier than 6 months but they said he's too little to tell if it needs to be an operation or not... so we're waiting the 6 months anyway. just wish I was asked what I was expecting before they spilled out the outcome of what is going to happen. the explanation was great, just felt like my expectations were crashed.
