is nipple confusion or flow confusion a concern? where is the research

[Guest guest]

I know an IBCLC who uses a lot of bottles when EBM or formula supplements are

offered.

She does not believe that standard pre prepared formula nipples or other nipples

will interfere with breastfeeding.

Demonstrating cradle hold fast bottle feeding in the presence of the family,

does that interfere with teaching breastfeeding to parents of a newborn.

Is there research or documentation to justify using cup vs SNS vs bottles in the

early days.

I have searched for several hours on line but have not found anything that

states the need for SNS/ CUP vs an artificial nipple.

I appreciate any information pro or anti artificial nipples!
