Ds2 is an erratic sleeper. He can sleep through but only about once a week. The only way he settles back to sleep and to sleep at nap and bedtime is with a bottle. In sleep deprived desperation we let him do this but now that I am getting some sleep and beginning to think again, I know this isn't a good idea. He isn't a good enough sleeper to just go cold turkey and take the bottle away but should I swap it for a dummy as an interim measure? Any advice would be much appreciated. Thank you!
