We are in the same position as traveller, with almost 8month twins we went from 2 to 4.....don't stress or worry about getting out too much...you have a NEWBORN....this time is hard to get out whether you have 1,2,4 or 10 children!! I'm sure if you think back it was also hard when you had 2 and your second was only 4weeks old too...I FREAKED out multiple times when DH was going back to work and really wondered how I would do it but just givew yourself some time..it get s way ewasier and yes some moments i really wish it were a kindy day lol and other days I'm fine!! I don't often go out with all four..not by myself.,.i take them on play dates etc but even though there it's with mums with kids of their own a lot of the time, at least there is another set of hands and as far as the shops by myself with all 4 NO WAY! My older 2 r in kindy 3days a week which is sooo helpdful because i'm a student midwife so I study around our babies. I agree with online shopping...more than worth the delivery fee and if you don't already maybe look into some childcare..honestly it doesn't make it a bad mum, kids love it and if its good for you it's good for your kids!!! I've loved having some mummy and baby time too, it's like havinf the freedom of one baby with the benefit of experience!!
