basically, you won't bring ah b out during the first two month, only to the doctor, so, you hold him/her is better, ah be will feel more safe. around 3 months, you can put inside the baby car to go out.
you should try to use the carrier if you go out with your newborn baby, so you don't have to hold him/her all day long. After a few months, you can put your baby in the stroller...
To be honest, it's hard to stay at home 2 months long, I just brought my 1-month-old baby to go for dinner. :mrgreen:
