DS2 is 12.5mo and currently naps 10am until 11.30 and then 3.20 until 4pm. It is getting increasing difficult to get him to sleep for his afternoon nap and I'm sick of fighting him over it so think it's time to go down to one. Bedtime is at 7.30, he is usually asleep by 8pm (late due to late PM nap). Gets up between 6 - 6.30am, wakes in the night sometimes only once, sometimes up to three times. The reason his PM nap is so late is due to picking up DS1 from school at 3pm - he won't sleep in the car so has to wait until we get home and can go into his cot. I'm worried about having an overtired baby on my hands but current routine not sustainable really. Would would be the best way to go about it?
