OK, I'm back.
So, it's been a month since I first asked about jigsaws. He did all the new ones, including the 100 piece then stopped, didn't touch one for about two weeks. Now he's back on them and doing between 4 and 10 per day, sometimes the same set (a book set or box set) over and over in a day but will also do both 54 piece jigsaws a couple of 45 piece and a 25 piece all in one day!
The 45 piece is taking all of 5 mins or less and the 54 piece just 10 mins. It's not exactly a challenge although I can see he enjoys them.
So, my question is this. Do I need to be getting more so he has a bigger variety (different 54 piece puzzles maybe?) or just let him keep repeating these until he passes out with boredom before I introduce more? The 100 piece is asked for on occasion but rarely tackled, I'm starting to wonder if it's the picture he doesn't like so much (Disney princesses which he appeared to like initially but now I'm not so sure), but don't know, maybe it's because it's 100 pieces and it takes some effort, or it could be that every time he asks for it he is already too tired to cope with something more difficult (he's just dropped his nap 2 weeks back).
Any thoughts? (I sort of hoped we could spend a bit longer doing these puzzles whether independently or together)
