Who said crocheted garments are not for boys?! I think this sweater will be perfect for your little one. Of course, it can be made for a girl as well, but cables and v-neck is just what your boy needs! Please, check the gauge for each size before you start. Finished Chest: 1-2 years (3-4 years) " 23 1/2 (271/2 ) in or 60 (70)cm Finished Length: 1-2 years (3-4 years) " 13 (15) in or 33 (38) cm SIZING / FINISHED MEASUREMENTS Pattern is made for one size, but I suggest to work: with sport weight yarn (FINE 2) and crochet hook 3.25mm (D) for size 1-2years with DK weight yarn (LIGHT 3) and crochet hook 3.5mm (E) for size 3-4years You can use also thicker yarn - worsted weight yarn for example, to make it even bigger, but for this I don't provide gauge and amount of yarn needed.
