Don't worry about routine, just use your time to rest, recover and bond with your baby.
Don't worry about a messy home. You can sort that out when you are upto it.
Breastfeeding or bottle. Totally your choice. I tried so hard to breastfeed but struggled due to not producing enough milk and being very anaemic after C-section blood loss. After one month I combined the two, after three months switched to bottle as baby wasn't get enough milk.
Sleeping? Each child is different. Some sleep 2 hours, some 4 but hardly any sleep more than that. Anyone tells you that may be exaggerating. Ensure baby's feet are close towards cot end. Avoid cot bumpers.
Bathing: Top and tail daily, bath once or twice a week. Babies don't get dirty. They are not on their hands and knees. Just make sure you wipe well in the crease of their neck and behind their ears where milk might trickle into.
Clothes. Buy lots of sleepsuits and babygrows and a sleeping bag is great to prevent baby kicking off blanket in the middle of the night.
TIP: I used to politely ask visitors to wash their hands if they came from travelling on public transport. They will understand. Last thing you want is your newborn getting an infection.
Overall, do what works for your. Listen to advice but it's your choice whether you abide by it. Every baby is different and I'm sure you'll do great with yours. Best of luck x
