I wouldn’t allow myself to be in a situation that I was uncomfortable with. I would keep the baby in your room by yourself. But that seems kind of creepy that he wants you to move into his room…
Second thoughts are totally normal, I had them for a month straight- actually at 6 months, too. I even looked up adoption online and called in about it. I realize that I could never give up my son, especially because my situation is very fortunate and his father and I would be a wreck not knowing where he’s going. Most adoptions actually become closed these days due to the faulty legal situation in the United States, so you really need to find a trusting family if you are going to put your baby up for adoption. But I PROMISE you, these thoughts will pass as soon as you hold your baby in your arms. It’s very scary to be pregnant period, much less young and pregnant, so just hang in there. 🙂
