Thanks brenda
I've tried shortening the A time, and that means that he ends up with A for 45 mins, asleep for 45 mins, then I have to find some way of settling him for 1.5 hours till his next feed - impossible with a toddler!
What do I do if he only sleeps for 45 mins, but isn't happy to be awake afterwards - I'd end up feeding him every 1.5 hours? I love our sling, as does he, but he is simply too heavy for me to carry for 1.5 hours.
What sort of age do they start to get the 1.5 hour naps? I can't remember how old DD was when she became the good sleeper that she is.
