Our little boy is 2.5yo and has slept through for over a year and has always been a good sleeper...for the last 2 weeks he's playing up going to sleep and shouts and cries for me (mom)...then during the night he's waking once and taking a long time to settle back off...the other night he woke at 2.30am then his nappy leaked so didn't settle back off till 3.45am...nothing has changed with his routine and still has an afternoon nap...he goes straight down for his afternoon nap which we don't let him have any longer than 2 hours...could this be a growth spurt?? Any advice appreciated xx
