Wow its great that you husband talks to your bump too.
Especially now that hearing is developing, it means that your baby will recognise hs voice too when it is born, although it may still prefer yours as womens voices are more sing song and of a higher pitch.
No, its not weird at all, keep talking, tell it about your day, what you are doing, what you think and feel - would you feel silly doing that if your baby was in a buggie? It's no different you are your sepcial baby carrier - be its tour guide hehe
