Jo, your inlaws are starting to piss me right off, so christ knows how you're feeling. You are SUPPOSED to be this size at 16w... especially after you've had brekkie and you start to bloat. I look absolutely HUUUUUUGE in the afternoons. Tell them your ONE baby is fine, thank you very much, and you are progressing normally. As for her not coming out in November - her loss.
You must miss your mum so much - but she's watching over you right now, with little Flumpetta on her lap xxxx
