I just read somewhere that between the ages of 4 and 5 months, babies go through a big developmental spurt. This requires their brains to make lots of new connections, which is done during periods of light sleep. Babies of this age therefore spend more time in light sleep, which can account for their more frequent night wakings.
Do you think this is true??
If so, it gives me hope that Adam's current penchant for waking 5 times a night for a winge/chat is temporary rather than permanent!
