Finished measurements:
Size 9-12 months: 58 cm (22.8”) chest, 33 cm (13”) full length
Size 12-18 months: 62 cm (24.4”) chest, 36 cm (14.2”) full length

I have designed and knitted this cardigan for my daughter and as she was a really big baby, the pattern is more suitable for bigger toddlers or even for children older than 24 months. Please double check the measurements.

Please, let me know if you find any mistakes.
