Konny baby carrier

You can try do exchange with carousell seller. And if you just give birth and feel tight to fit I suggest you wait awhile before you sell. I gain 22kg during pregnancy after give birth I bought S and M size but S can't fit very tight so I sold away the S and kept the M. But 4 months later I slim down the M now is very big for me but still usable am still using 13 months now very useful.
