Hi all, this thread moves so fast. I can't keep up!
Been taking it easy as I've had a big SPD flare up and am trying to be really careful while it settles down. Feeling a lot better today, thankfully.
I had a long look at doubles magic but decided to wait and see as they are so expensive and look heavy and bulky. Also, most of them won't allow baby to rear face which I want for the first few months. The best one I found was the baby jogger city select double so it might be worth looking at that. Today, I've been looking at buggyboards and saw that the universal Lascal maxi can come with a saddle for the little one to sit on. I think that seems like my best option as I'm not how long DS will stand when he's only just 2. The two together will be about £100.
My scan is tomorrow as well lemons! I'm finding I'm less excited this time knowing we won't be finding out the sex... seems to me I'm just going for the 'anomoly' part without the exciting reveal at the end. I'm sure I'll get excited when I see little bub on the screen tho 
Beano, I prefer my wrap sling to the soft structured as it is more comfortable and conforming and felt like I could get it really secure around my son. I have a manduca soft structured carrier which is great but always felt like my son slightly got lost in it when he was small, even though he was a 9lb-er! I would recommend you buy a fairly cheap stretchy wrap and then find a sling library to try out other more expensive brands once you have baby to try them with. Just don't buy a baby bjorn!
