Yes, it will be hard. He/she will pee and poo on your floor with alarming frequency at first. You won't be able to take it out for at least a month because it won't have had it's jabs yet.
In terms of toilet training, they need to go out every twenty minutes when awake, after meals, after drinking, and during/after each play session. I wouldn't use puppy pads as they encourage peeing in the house, so you'll need to take them out 2-3 times a night for the first couple of weeks. Ours didn't sleep through consistently until he was seven months old, but some have stronger bladders than others.
Generally the rule of thumb is they can go an hour/month of age plus one hour. So if you have a 2 month old pup, they'll be able to last three hours maximum overnight, less during the day.
Puppies also teeth, chew, bite and nip. Do you have young children? You need to teach them how to deal with it and prepare for them to HATE the puppy while it's teething. Puppy teeth are like needles and they bloody hurt and will probably draw blood a couple of times. You'll need lots of teething toys and chews that are suitable for a puppy.
Are you going to crate train? How are you going to cope with that during the night? If you're not going to crate train, where is the pup going to sleep? Is it puppy proof and can you get to him if he needs to get out in the night?
How are you going to cope with going out all day? You can't leave a tiny puppy for long at all - maybe an hour or so max at first. What if you want to go to the zoo or the cinema? Do you have someone who can watch the dog for you? Do you live in a dog friendly area? Can the dog come to town etc. with you or will it need to stay at home? And if so, are you prepared to cut days out short so you can get home for the dog?
In terms of walks, cockapoos are very high energy dogs - you have a combination of two high-energy working dogs. Can you dedicate the time to walk them for at least an hour twice a day (when fully grown) every day for the next 12+ years? You can't skip walks because it's raining or you're tired or have a cold. We have a high-energy working breed (beagle) and he's a nightmare if he doesn't get his walks.
Have you factored in the necessary costs? Leads (yes, multiple, they will chew through at least one!), collars and harnesses (replaced as they grow/wear out), food, chew toys, blankets, beds (again, they will chew and destroy them), insurance, puppy classes, flea/worming, annual vaccinations?
Not trying to put you off - I love our pup and haven't had anywhere near as many problems as some MN'ers seem to have had with theirs, but he is a lot of work and has taken over our lives. Days out have to be planning around his needs, you have to think about whether he can come into cafes or pubs with you, whether you can take him on days out, whether the beach allows dogs in summer etc etc. And be prepared for the puppy blues!
But saying all that (sorry it was an essay!) ours is amazing and so worth it. He's eight months now and settling down massively. He goes to weekly classes and has started doing very basic agility this week. He walks to heel (most of the time@), can be let off-lead, loves playing with other dogs, knows a fair few tricks (except roll over, he refuses to do that one!), comes back when called, is 100% house-trained and sleeps through the night. He's an amazing addition to our lives but the first few months were HARD.
