Highs and lows

MashaAllah, I'm happy that my children are remaining children, not growing up too fast, not losing their childhood. But the other day my eldest came home from school a little sad. His classmate who's a year older had been teasing him that he din't know anything about drugs were, even 'snuss' which is tobacco/ snuff stuff theyhave here in Sweden. So I'm googling to find something appropriate to give him the information, because forewarned is forearmed I suppose. Does anyone know a good website at a 10-11 year old's level? (Swedish and/or English).
Generally I'm feeling a sense of 'disquiet' at the moment, seem to be getting all over-anxious about things. The house being so full of mess, not feeling I have enough time or energy to do much with the kids (former due to them being at school, latter due to having no 5).
Alhamdulillah.
And it's only Ramadhan keeping on track with ibadah that makes me feel I am 'achieving' something.
But in fact Hz is sleeping pretty well. he can go 6-7 hours at night without waking, and he's started sucking his thumb which should help with sleeping, rather than having me as a dummy.
He's found his hands and has started lashing around with them so much that I've had to find a nail file to sort out his fingernails, to stop him scratching himself so often. Cutting them wasn't working, it's so hard with little fingers that are being flailed about to do it properly.
Biryani's potty training, uh oh, this has gone out the window and back into nappies, and also started doing poos in them which she never did when we were first training. I know its normal regressive bahaviour due to baby arriving, but its v difficult and strange to clean her (after she's sat down in her dirty nappy, ugh) after such a long time using the potty for number 2's.
Other regressive feature is she's started speaking with sound immaturities e.g 'fis' for 'fish' and sometimes 'labbit' for 'rabbit'.
Ho hum
It's the last 10 days now of Ramadhan. InshaAllah we can make the most of it...
