there is no way you would be able to make anything big enough for a baby with the size of needles and DK weight yarn that are used in the pattern
Looking at the info on ravelry it says 3.75mm needles and a gauge of 5.5sts per inch. That sounds reasonable to me for DK (although I personally would need to use 4mm possibly 4.5mm to get that gauge).
It doesn't matter if you use different needles than the pattern states, the important thing is that you get the gauge right, toherwise the finished size will be different than expected.
