Um, yes LargeG&T, of course Levi is nearly four months weeks old now, how clever of you to know .
Oooggs, no advice sorry, but sympathy. Ds4 is very unsettled between 6.30-8.00pm while I put the others to bed, and its really hard work. Ideally, I like to get them pjama'd, teethbrushed and have them drinking milk in their rooms, then two stay and 'read' and I take the other one for special time (practising ds1's reading and writing, listening exercises for dt1 and speech therapy stuff for dt2, all disguised as fun activities!). This kind of worked for a few weeks, but now Levi is so unsettled (and I'm usually so knackered) that its all keeps disolving and I inevitably throw the older three in their room at 7.30 with the light on, then feed Levi just to keep him quiet. If dh is around, he does try to occupy him while I sort the others, but he is a typical man in that he jigs him for a little bit (noisily in the background so I end up rushing special time), then says, 'I can't do anything with him, he must be hungry.'
