You are doing a great job!

1) You can breastfeed anywhere you want to.
Breastdeeding on the plane would be a great way of having her settled on the flight.

2) colic/reflux/wind - not sure maybe ask your child health nurse or GP.

3) you cannot spoil a baby under 12 months old. Please don't leave her longer than 10 mins ( and I am not suggesting that you are).

Sometimes Milo would be unsettled for hours unless he was in my arms. Do you have a sling?

Also, keep in mind you are in week three - growth spurt time - so she is likely to be more unsettled than normal.

maybe check out the wonder weeks book if you have not already?
