DS2 is 11 weeks old and though he needs several sleeps a day he'll only have one of them in his swing (no chance in cradle)... If I put him down for the others he wakes within a few minutes if not immediately. If I persevere putting him down every time he ends up so overtired and cranky that he won't fall asleep until about 11pm.
If I end up holding him for his other naps it's very difficult for DS1 as I have very little time to focus on him.
This has also coincided with DS2 crying if anyone other than me holds him for more than a minute.
I attachment parent, we cosleep at night (he's a colicky baby) and he's in a sling when we go out but won't let me sit down for a moment in it at home, so I still can't do activities with DS1.
