Thanks for your replies everyone. I'm definitely not worried any more. I guess I just haven't spoken to enough people to realise this is normal, cos I was still wearing pads for months with Tully.
The last 2 nights I've gone bra free, only to wake up leaking everywhere because Felix has slept through to 6am!! The first night I thought it was a fluke but he did it again last night. Fingers crossed he does it again tonight. They say 3 nights running is a pattern huh?
BTW, the muslin tucked in to the opposite breast is a great idea. I can't remember - Does the opposite breast always leak or does this stop eventually too??
