Don't have a 14 week old anymore but more than happy to share our routine at that time. We pretty much followed the one laid out by Tracy though, except first A was only an hour.
7 - I woke her up + feed 1
8 - 10 - nap 1
10 - feed
11.15 - 1 - nap 2 (almost always needed a resettle. I kept A time to 1hr15 mins)
1 - feed
2.30 - 3.15 - nap 3 (always 45 minutes, with an A of 1.30. Never managed to resettle)
3.30 - feed
Between 5 & 6 - CN of 45 minutes
On waking from CN - feed
Bath + massage
Bedtime feed
7-bed
Between 10 & 11 - Dreamfeed
Hope that helps:)
