I used carrier for my both babies. Though it was much beneficial during second baby as I could equally manage the elder one.
Advantages of baby wearing :
1. Makes everyday life easy - I could go shopping or walking hands free.
2. Best while on a holiday.
3. Great with breastfeeding - I could feed my children anywhere anytime without looking for a feeding station.
4. Kids are less cranky as they love being close to mother.
5. The best of all I could ride a two wheeler while my baby is with me safe in carrier.
I support baby wearing...
