How long can/did you use a sling when pregnant?

[Lancrehotpot]

My DS is 10 months and I am 16 weeks pg with DC2. We have a pram which I use mostly for road-walking, but often use the sling (wrap) for bus etc. He is a tall boy and has been carried on my back recently as front is too uncomfortable. Can anyone tell me how long it's advisable to carry him like this for (pregnancy-wise)? I am not uncomfortable, but am aware that I will rapidly be running out of waist room

As long as you're comfortable it's fine :) I've known people still wearing toddlers until days before labour - doubt if I'll manage that but it's certainly possible!

Best carries tend to be a ruck tied Tibetan, or a Double Hammock as neither of these need to be near your bump, YouTube has loads of videos of these in action.

Thanks Rockchick; got into a rut of doing the same ties so I will definitely check those out.
Don't think I'll be managing up to labour either!
Can't say I'm looking forward to the disapproving comments from relatives though.
