The jumper in this pattern consists of four pieces, the back and the front and two sleeves.  The kind of neckline in this baby sweater knitting pattern is often called a boat neck and is straight rib with a little shaping for the shoulders.

The style of neck on this basic baby sweater is particularly good for infants as the opening at the neck is quite wide making it easy to get the jumper on and off over their heads.

I used Bendigo Woollen Mills Luxury 4 Ply Baby Yarn to knit the example of the sweater produced using this basic baby sweater knitting pattern.

Approximate sizing for this pattern is 000 (newborn to 3 months), 00 (3-6 months) and 0 (6-12 months), but remember not all babies are the same size at the same age.  It might pay to check the infants chest measurement before you start knitting!
