Your child does have to learn if the puppy is sleeping them the puppy needs rest- but on the same note no matter what the puppy should not be biting- I would def nip this in the butt now- he's 5 months old so still needs sleep but not as much as a 8 week old pup needs...
I would pick up all food and teach your pup some manners- have your daughter to tell pup to sit (if pup does not sit then you enforce it doing the down with the bum as your child says it) and have your daughter put the food bowl down do not let the pup have his food until your daughter says its ok- Always make sure you are there- this way your pup will see your daughter is where food is coming from and will learn to treat her as alpha over him and not another play mate. I would allow your daughter to give pup treats but only once pup does a command like sit, down, come ect and take it nice- you can even have your daughter feed food as well. I would also pick up all toys cause if pocessive over food may be over toys as well- have your child offer a toy to play with for a bit then take toy but always offer something in return like a treat or another toy this way he see's your not just takling stuff away he learns to give things up cause in return he gets something back and won't be possesive. Always use a command word to get the toy like drop it- good pup treat or another toy.
Never leave pup and child alone ever- so many things can go wrong that you do not see and which can turn your dog mean real fast.
I have always had my children play with the dogs food when pups and they to were lil and give food, hand feed which ever cause I would not have a dog that would snap while he/she was eating- as far as Iam concerned the food is mine and only yours when I say so. I do free feed my dogs and have never had a problem with just taking their food away, be it a treat or human food my children can do the same as well, take it right out of their mouth. Yes may be boston terriers but we also had a shepherd/collie and a wolf/rotti (R.I.P)which we all did the same with. They would be eating their food and my children would stick their hand in the bowl they would stop eating and they would grab a handful and hand feed them lol they didn't care and thats what I liked to see in my dogs.
You never said how old your daughter is-
Even for sleeping my children always woke my pups and of course I would say let them sleep and make sure they got their sleep but sometimes they would wake them and not once would they attack or growl- my kids would even crawl in the kennel with them even tho that was their bed its ours I only allow them to use it lol
I did have one boston when woken would growl and go to bite- I spent a whole day bugging him, once he fell asleep I would wait a bit then wake him cause I didn't want my children getting bit. I made a habit of holding him when he was sleeping- he started this at 4 months. After about 3 days of this he stopped cause it got to the point you couldn't even walk by him when he was sleeping. Sadly at 8 months I ended up sending him back to the breeder because I was told he had 2 testy's which he didn't and she said oooh give it time it will drop, and he had alot more problems could not breed him. I was gonna ask for some money back but she just sent my money back and I put so much time into him :( long storey- wish she would have gave me some of my money back cause he had contained teeth, tumors starting on him, unbilical herinia needed surgery ect ect at just 8 months.
