BNWT!!! Never used VIJA kangaroo shirt! Size Large. Now you can wear your baby!!! So so convenient! As long as baby is under 15 lbs they should fit in the shirt nicely. I have kangaroo shirt and absolutely loved it! I purchased this one and forgot I had it until Baby was too big the shirts run a little on the small side but you do want it to fit snuggly so baby is safe inside. Originally paid $79.00 for this shirt. It is currently $75.50 on Amazon.
