What do you think?

I've heard with twins, one will be smaller than the other and might lag a little behind picking it up. I'm currently at 27 weeks 4 days and my babies last weigh was Baby A 1lb 8oz and Baby B was 1lb 7oz. They were weighed again today and Baby A weighed in at 2lb 4oz and Baby B weighed in at 1 lb 13 oz. I was bummed because baby b didn't gain much from the last weigh in bit doctors say she is fine and they both look great. What do y'all think? They are going to be delivering around 32 or 34 weeks is what the doctor is striving for but I won't be allowed to go past the 34 wk mark they tell me. My twins are mono twins, same sac, same placenta and I was just wondering if other mommies who had twins or are having twins what do you remember your babies being measured around the 27 week mark..
