I'm struggling right now with what to do - I was quite happy to let my 4 month old suck himself to sleep and would happily let him come into our bed, he always sleeps better there & I don't believe in «training» babies to
fit in with our schedules... However, from being a «good sleeper» he's now nearly 5 months and his sleep has deteriorated to a 2 or 3 hr stretch, then he's up every 45mins / 1 hr or so
throughout the night - not fully awake but
crying for a feed to get back to sleep.
