I have lived with these children when they turned 18 and went to uni and Mummy had done everything for them. They couldn't cook, clean, use a laundrette, they were my first year house mates and I hated them. Nothing worse than wanting to cook and finding 4 day old plates piles high in stagnant water it the washing up bowl. I used to lift it out the sink, wash my stuff, put theirs back. Thank goodness I had my own pans and crockery.
I also have a 16 year old about to sit GCSEs who is already on Easter break and revising. He helped make pulled pork last night and the salsa that went with it.
@PookieDo I think what you are asking is completely reasonable. My two sons 16 and 13 help prepare meals, the 16 year old is off duty because of revision but can make about 3 different meals for the family because he has learnt. It is a nice time together.
Dinner is eaten around a dining table which they set together, we all clear away but they children stay in the kitchen until everything is in the dishwasher or handwashed because they understand the importance of learning how long things take.
They know that the 1st week of the month is me cleaning out the dishwasher trap, the tumble dryer filter (the big one) and cleaning the iron out (steam generator.)
They strip their beds, make them, their rooms are tidy, they each take responsibility for one bin each (recycling, kitchen) they are emptied twice a week on set days so you never have an overflowing bin and they do it as they leave the house for school. They also hoover their rooms once or twice a week.
I am a SAHM and I am teaching them to be fully functioning adults. Dh was raised by a SAHM who taught him everything too so I didn't marry a lazy arsehole when it comes to housework.
All the people commenting about how long things take have probably got a tidy house and it is easier to keep that clean and tidy but when it is chaos to begin with it is much more difficult.
I highly recommend The Organised Mum method. It's 15 minutes of daily, plus 30 mins of specific. Have a look here scroll down for the specifics.
Being a lone parent must be hard. Everyone should be helping out, not saying that's not mine.
