When I first conceived DH and I would call bubs, Jelly Bean and this continued on until about 15 weeks when we saw the u/s and changed it to Jelly Baby. Now I just say "bubs" or "my sweety". I know it's a girl but even though I'm pretty sure we have the name I'll still wait until she's born before referring to her as such, just in case I look at her and think "no that name doesn't suit".
