Just wanted to say wow, well done for surviving! DS is 4.4yo and DD 2.2yo and that's hard enough for me! When DD was a newborn, I used to find it really difficult to entertain DS, so would spend a bit of time in the evening preparing stuff for the next day, I even did a list of all the toys/activities and left it on mantlepiece, so that if I had a spare 5 mins for him, I could choose something different each time, rather than going for the same boring thing for him. Just wondering if you could prepare things that way for DD - I often find that if I spend 15 mins helping them both set up toys now, then when I slope off to catch up on a job, they don't really notice as they're playing happily. (Not suggesting for a minute it will be this easy for you with 4 though!)
can you set somethign up for the boys one side of the room, and somethign else for DD?
I know I don't have any useful advice, but hopefully bumping for somebody else to come along, and also, isn't there a thread for mums of multiples? that might be more helpful too?
hope you get some good advice soon. (and can DD start play group in sept? - couple of hours for her every day might help you all?)
And I know you say you don't like to ask, but ask ask ask for help off the in-laws if they're prepared to do it. - even if it's short term to help you manage it all, or give you a break to have one on one time with DD, whilst they watch the boys, or even... time for yourself!!!
