Hello all! My scan went well, I finally feel like I can actually say I'm pregnant!
I have been very superstitious about this whole thing, but I am trying to make an effort to relax now. The baby was sleeping at first so she did the measurements, then it woke up and started moving around, and turned it's back to us. It really looked like it was trying to get comfy, and away from the prodding. So real to see him/her in there. She gave us a DVD of the scan, and we showed my three-year-old. He watched very solemnly, then said 'I'm a big brother'.
Regarding co-sleepers, we had this one which I used for six months, it was great as had baby right next to me for breastfeeding, but he was on a safe mattress with no chance of quilt going on him. If you look at second picture, it shows the side of cot comes off, then it straps securely to bed so no gap. Means I could breastfeed sleepily, then roll him back in.
I am in US so got mine here, but sure you can get something similar in UK.
