Izzy has always been outward facing, always. since newborn. So Izzy has been

for the majority of her life (on my front) she didnt spend a lot of time in her car seat or push chair at all, pretty much using them for naps. SO if her eyes are closed what the hell does it matter which way she faces

On the odd times she is awake i actually think it is a nice change for her to face out and look around instead of at my ugly mug

I don't think people really need to be sad about my daughter facing out in her pram! Those who have met me know how much love and attention she gets!
The answer to your question is "whenever YOU want" I think it is each to their own really.
