You will cope fans honestly. Some tips from my 3 months of ft working so far:
A cleaner is essential I find. Washing gets put in machine at night and hung up in the morning. If your cleaner also irons then even better. Buy Nigel Slater?s Real Fast Food (lots of nice 20 min meals) and a good pasta book with loads of recipes that take as long to make as the pasta takes to cook ? ie carbonara, or one I do which is sundried toms, jar or antipasti peppers, chorizo and parlsey, fried in the oil from the jars, mixed with the pasta and some parmesan. Takes 10mins tops and is really yummy. Also batch cook where you can ? ie if making chilli, curry, spag bol or a pasta bake I make double and freeze half. We do eat more jarred sauces than we used to (I always used to make curries for example but now have jars for curry unless it?s the weekend).
Shopping either gets done online or at lunchtime. If they don?t sell it in tesco extra 5 mins from my work, it doesn?t get bought!
Make sure everything is ready the night before for the next day ? ie kids change bag etc for nursery, your sarnies for lunch etc, and do everything when you get in from work before you sit down. I find if I sit down first and then think, I?ll do it after dinner, it doesn?t get done. Oh and be prepared to not eat till 8.30/9 most nights!
Did you find a nanny or are they going to nursery? If nursery, get them to have the evening meal there if poss. Artie has his tea at the cm?s at 5 which means that when we get home at 6 we just have playtime till he goes to bed, and it?s also one less thing to think about. We just give him breakfast ? but tbh she?d give him that if we wanted her to.
