How to do this? 3 month-old DS can fall asleep quickly if we catch him at the right time and use the strategies that work for him (sling or a walk in the baby carrier the best), or if he happens to be sleepy and hungry at the same time. But if we don't use these approaches he can easily just stay alert and awake and simply get increasingly grumpy/upset.
Problem is that our current approaches are pretty tiring and limiting, and mean that he is far from napping in his cot. Even in a deep sleep, when I try to transfer him he seems to keep waking after 2 mins. So I figure life would be easier if I can gradually 'train' him to go to sleep in his cot in the first place. Strategies...?
