We already have an old Macpac that was my SIL's and we are now using for our 3rd child (12mths).
However, we are hoping to start doing some longer hill walks over this summer and will definitely need another carrier for our almost 3yo dd, so that she can be carried when she is too tired to walk anymore. She is very light- approx 10.5kg.
Ideally I am looking for something small and lightweight but comfortable as I will be carrying her and dh will be carrying dd2.
DS (4) will probably determine how far we can go!
