Posting here for visibility. Got a 7 day old daughter. My milk didn't come in until day 5, so she had to be given formula to top up (midwife advice), whilst I also expressed to increase supply.
Milk is now here, she is feeding every couple of hours, currently cluster feeding, so she is only getting formula if she seems very hungry (twice today 30ml). But, she has only produced one poo per day, for the last 2 days. They have been massive though, including an explosion!
AIBU to worry that she is not poking enough or breast feeding effectively?
