Am trying to instigate a daytime nap routine for my DS who turned 12 weeks today.
Ideally I'd like to put him down after his lunchtime feed for an hour or two. I've been trying this for a week (blackout curtains closed, quiet etc) and it isn't working very well. He seems to fight it. I try rocking him, holding him (don't mind if he falls asleep on me the first few times, as he's good in his cot at night), but he does not appear to want to get into a routine just yet.
Is it too soon? I've got a friend who said she was putting her 8 week old down for 2-3 hours every afternoon! 
If he doesn't have decent sleep in the day he gets very grumpy in the evening, and then collapses on me in the evening.
Any tips/stories on daytime napping greatly appreciated. Thanks.
