It's different for everyone so you can't assume that you'll have an easy recovery, but you might do. Planned sections are usually far smoother and easier to recover from because you haven't laboured, often for a long time, first and they're not done under emergency conditions. However infection and other complications are still possible and overdoing it can be a massive mistake.
I had one emergency and two planned sections. The emergency involved all sorts of problems and was difficult to recover from. One of the planned sections I recovered quickly, but the other I did too much too soon and set my recovery way back, started bleeding again very heavily indeed and experienced a lot of pain, so don't blythly assume you'll be doing iron man competitions at 10 days post section with the baby strapped to your front and toddler on your back, just because a competitive competence type in the internet was.
Be careful about what help you accept - only accept help which won't actually be a hinderence and stress you out and create emotional and physical work for you. My mum came to stay after one of my sections and I knew it was going to be awful before hand, but everyone says accept all offers, and my dad emotionally blackmailed me saying how much she wanted to help... It was awful. She took the newborn and wanted to hold him all day (I was breastfeeding and had just started carrying him in a wrap a couple of days before she arrived and hated being physically apart from him for long, plus she rocked him to sleep when he stirred meaning he didn't feed enough in the day and reverse cycled, feeding all night but I was with my non napping 2 year old all day). She didn't help except by "holding the baby" and criticised me endlessly for not getting on with a good housework blitz while she was there "to hold the baby" - ten days post section! She didn't so much as make me a cup of tea but expected to get up at 8am, spend an hour in the only bathroom (newly potty trained toddler in the house) then sit with the baby and be waited on all day. It was so awful, and when I tried to talk to her about how I wanted actual help and my baby back she cried and said that she'd come to bond with the baby. It was so awful. So don't accept "any" help, think carefully about whether it will be genuinely helpful.
I very much do not recommend having anyone stay in your house until you are recovered yourself. Visitors who visit for an hour are great, ones who are still there in the evening when you need to Clusterfeed or in the morning when you need to be able to get into the bathroom in whatever random window your toddler and newborn are both asleep/ newborn asleep and toddler happy to play on the bathroom floor are absolutely not.
Certainly accept help getting your toddler to nursery if she's already established at nursery though!
My 2 year old was in a cot but with 2 removable bars like a little entrance and exit so she got in and out herself. With my 3rd section the toddler was in a bed already. You shouldn't lift her into a cot.
When you first get home you shouldn't lift the car seat plus baby, nothing heavier than the baby. Don't change the baby on the floor - you won't be able to get back up with the baby in your arms nor pick them up from the floor. You need a changing table or solid, wide table set up as one.
Set everything up downstairs and buy new DVDs and whatever toys or crafts your toddler can play with as independently as possible in the room with you and keep them in reserve for your first week or so alone at times your toddler isn't at nursery.
Order shopping if that's an option where you live and pre cook before the birth and freeze or live on easy stuff like pasta and jacket potatoes. You may not be able to stand for long.
You can easily cope alone from 2 weeks post section but do not try to be superwomen as you risk setting your recovery back.
