Dont know what to do! We've bought hip seat carrier and I feel bad coz i told them not to use it. I've read articles regarding hip seat carriers and it's not advisable for infants. What do I do with the carrier?

How old is your kid? Most articles and even babywearing groups say hipseat carriers are non-ergonomic. So they don't recommend to give it to others. But some owners, being practical, use it for their kids as long as they are 1 year old and above.
