DS (18wks)- we've followed his lead 95% of the time. The other 5% we've tweaked.
He feeds every 3 hours in the day. He is FF at 7am, 10am, 1pm, 4pm, 7pm. The day feeds are about 5oz. The 7pm feed is 8oz.
He naps when he wants to in the day. This week he has woken at 7.30am, back to sleep for 45mins at 9am(ish), 2 hour-ish nap about 1pm. Quick half hour at 4pm. He will not nap on his own though, only on me which is not so good, but I quite like it!
By 7pm he is ready for bed. PJs, gro-bag, feed in dark room. Place in cot sightly awake. 7.15pm- asleep. He wakes at 5.30am for a quick 10min snack (3oz) then goes back to sleep until the alarm.
We try and pack more milk into him in the day. If we feed him later than 4pm, the big 7pm bottle is not drunk fully.
DD on the other hand didn't sleep through until she was nearly 4yrs old and was still waking in the night at 18mths for milk! We've tried very hard with DS not to fall into the same habits we did with DD- failing though but he is just a different child that likes his sleep.
