Congrats OP. Don’t underestimate that you’ve had major surgery and need to allow 6-8 weeks for initial recovery but that full recovery will take up to a year.
Get moving as soon as you can, gentle movement will help
Regular pain relief and staying on top of this when you get home too. Take all the pain relief you need and are offered, no medal for struggling with poorly controlled pain
Don't rush home too soon if your pain isn’t controlled
As much rest as you can get
Lots of pillows to get comfortable in bed and you’ll need help getting in and out of bed to start with. Pillows will help with your comfort when feeding baby too, whatever way you are feeding
Mind your back as it’s lost the support it normally gets from your abs as they heal
Stay hydrated and use stool softeners if you need to to avoid constipation
Gently clean and dry your wound every day. Hairdryer on cool can help to make sure it’s really dry after a clean or wash.
High waisted loose pants and clothes.
You can get silicone scar patches once it’s fully healed. Look up scar massage.
Accept all the help you can get
Straws and an extra long phone charger cable will be your friends
Get your shopping delivered
Allow yourself to recover mentally
Don’t be afraid to delay visitors until you feel you can manage this
Don’t be tempted to overdo it as you’ll set yourself back and slow your recovery
