Matthew had his done at 4 months or so. We did not do the general anesthesia, but they did sedate him. I would assume that for a bigger baby it is really just not possible to hold them in place as well as a smaller younger baby.
No, no pain medication because it should not hurt. I had a biopsy teh same day as Matthew (weird coincidence, right) and they gave me a sedative through the IV… i woke up and never felt anything they had done to me. Matthew was also fine after the sedative wore off…
Good luck! i hope you get some answers.
