Our LO is almost one and has just started waking in the night again. He has been sleeping through the night for the last 2 months (before that he slept through the night from 12 weeks until about 5 months and then we went through a phase of him waking once or twice every night but had managed to stop that.) Just wondered if this was typical around the 1yr old mark? We've recently changed him over to cows milk - would this have any affect on his sleeping? He eats really well through the day and has 3 full bottles of milk. The HV says there's no reason for him to need feeding at night given what he's eating during the day. Has anyone else had this experience?
