Sorry to bother you with another question, but when I get around to fixing the flaking paint in the bedroom, I should probably also do the hallway at the same time. Am I right to assume that I would just have to scrape off the paint in the affected areas, make hairline cracks a little wider in v-shape with a blade, then fill, sand and paint? Wondering in particular about the flaking paint along the edge between wall and ceiling. A builder who had a look said he would just put some painter's mate caulk, but that doesn't sound quite right to me.
Thanks so much!

Caulking the edges of walls is normal practice. It probably lasts longer than a hard filler. There are different qualities of caulk and it's helpful if it has a few hours to dry before it's painted over otherwise the emulsion might craze.
In the hallway the only thing I think would worry me is the little patch of what looks like a damp stain. Sometimes they need to be covered with something like cover stain because emulsion might not cover it.
I can't be sure what if it's just the photo though.

You would be lucky to get a painter in. Maybe if you had someone in your street.
I would try to scrape the whole lot to the left of the window off or at least score the paint in a straight line above the highest patch and scrape off below that line. It is the transition that shows but it's easier to fill and feather a straight line than a rough edge.
I use a 50mm scraper blade which is honed through use on plaster walls so it makes it easier to do without gouging. A 6" T handle scraper is likely to get it done fast and ensures you can get the small bits that are well adhered off but it's easier to gouge which means filling and it's not easy to fill small gouges. A plastic handle with a Stanley blade in is the cheapest option. If you're lucky it will fall off and maybe you have a tiny bit of sanding to do for any little bits that stick. I've stripped 20 times that area in 1/2 hour more than once.
If you are not sure the paint is badly adhered then you might want to skim the holes you have with filler, feather with a sponge and then lightly sand and paint. It will probably grin or flash a bit but you are not going to care after 3 months with a baby in the house. :)
good luck & bon courage
