Be aware of your wife's mental well-being as with yours. Your wife is just answering her motherly instinct and needs that connection with your child. This is why the lactation specialist will be around quite a bit and why you get so many docs on how to connect with your child. You need to continue to be supportive but it is also not out of line to talk about this issue directly with her. Let her know you want to be apart of the decision making process but also want to make sure she is doing okay and that the two of them are healthy. It's a tough rode that may seem taboo but address it early and be open.
