The thing is, if you love dogs you will risk the downsides to get one. But they aren't all a walk in the park. Even experienced handlers get problems with dogs that they struggle to overcome - and sometimes fail to overcome. The sorts of behavioural problems that can be very tricky include not being good with children, not being good with cats, not being good with chickens and other livestock, not coming back when called, chewing the house to pieces, being unable to be left alone, howling/barking and annoying the neighbours, fouling in the house, biting visitors, chasing cars, being unsafe in traffic, being smelly, running off/escaping, stealing food/raiding dustbins, being aggressive with other dogs (which makes walks a nightmare - ask me how I know)... I could go on. (Incidentally I have had dogs which have had every one of these problems.)
Then there are the health issues which you can do your best to avoid, but you can never have a risk-free purchase - so then you have a dog which may require carrying up and down stairs, short frequent ambles and no long walks or jumping or running, regular hydrotherapy, expensive operations / drugs (and which your insurance may not cover, especially if it is a congenital problem.)
Then one or more of the children may develop allergies - asthma, eczema, etc.
You're right with young children to avoid rescues / adult dogs - but then training a puppy is fraught with problems, especially when you aren't experienced, neither are the children, and even more so when there are cats and chickens about.
Tell hubby he can have a dog when the children are older and (a) out (of the way) more and (b) more sensible - and (c) you will have more time and energy to devote to the puppy too.
And if none of that works, find a good breeder of nice
pet Labradors and get a lovely Lab bitch pup.
