As a pediatricain I often see moms and babies "together". In fact
the baby is often latched and feeding when I enter the
room.
Today I saw two sets of breastfeeding twins. For one set
who were both fussy I examined one as mom nursed the other.
As number two nursed after his exam number one became
fussy again so I held him and stood rocking  and he feel
asleep. Over a year since my son has been fussy and I can still
do it!
