My second child is almost 7 months and really fights day sleep. My first child slept (still does) for hours in the day and I am not used to this situation at all!!
I think part of the issue is that being 2nd born we are on the go with our eldest and this means lots of falling asleep in the pushchair and car seat. How do you get a second born into a routine?
When I know DC2 is so tired I have to rock, bounce, cuddle them to sleep and I am luckly if them sleep for a 40 mins in the morning and 40 mins in the afternoon.
