Is it because of the babies surface area to volume ratio?

It's a matter of scale, period. Smaller mammals have higher heart and respiratory rates (and metabolisms) than larger ones.
What's interesting is that a baby has a metabolic rate like the mother's just before birth, but it roughly doubles in the 24 hours after birth and becomes characteristic of a much smaller organism ("the rapid increase in metabolic rate that occurs immediately after birth" - see link).

Their heart is smaller in ratio to their blood system than an adults is.
It must pump more blood to get the oxygen around that the baby needs. Also, the hemoglobin in utero is less efficient for carrying oxygen than that which the baby produces after birth.

Smaller heart
Almost all small living things have a higher heart and respiration rate than larger things.

babies have a higher heart rate than adults. it's common. and there respiratory should be normal.

that would be the primary factor. the baby is adjusting after placental circulation is interrupted and pulmonary circulation is established.
