hi we don't use a cot at all, our babys/toddlers have always slept with us, um during the day would you want to try boobing him to sleep on your bed and using a side rail to stop him falling out? and when you hear him starting to wake quickly go in and boob him again. or else have you a sling? oscar sleeps alot in our sling during the day or on our bed. that's my only suggestions.

re the pillow SIDS do recommend not to use one until after 1 year i think.

good luck
