If you were only able to express from birth how long til your milk came in?

[MrsFabuloso]

My milk is slow to come in too. I never had any leaking or anything before baby was born. It came in properly at about day 6 for my first (I had a traumatic birth, a big PPH and she was partly bottle fed), day 4 for my second and probably day 5 for #3 (significant PPH and bub was sick in SCN for a few days). I had colostrum, but my actual milk takes a while to set in.
