DS2 is 4 months old & during the day refuses to nap anywhere but on me. Even if he's asleep if I put him down anywhere he wakes up almost immediately. I've tried laying him down with an item of my clothing but no joy. I can sling him but I'm starting to feel a bit stifled by it all. Also have a toddler (3 tomorrow) & juggling both of them on my lap is tricky. What else can I do?
