I think my midwives poked a hole in a pad and put ice cubes in there - might be a quick fix worth knowing. I remember overlapping two pads too.

My main post birth tip is to have that wet flushable toilet paper (basically wipes for adults) - so soothing and handy for providing support during #2's.

Also for #1's, leaning forward, it's sort of like doing a handstand, lol, but you can avoid stinging. Taking Ural to neutralise the urine a bit helps too.

Clothes you can sleep in (think dance pants, cotton tops) mean you can answer the door or go outside essentially in your pjs. Handy for not worrying about visitors. A cardi/bolero thrown on hides bralessness pretty well.

Tinned soup is a completely acceptable dinner. I always forget about it and it's so easy.

That's all I can think of for now.
