My 5MO DS has been sleeping really badly lately - after about 6 weeks of deterioration he's now waking every hour to hour-and-a-half. I've pretty much reached the limit of what I can cope with so I'm thinking of giving him a bottle of formula tonight in the hopes that the heavier milk will keep him satisfied a bit longer. I don't want to give up breast feeding him yet, and certainly wouldn't want to drop the bed time feed any time soon, but I'm getting pretty desperate and need to get some sleep. Will a bottle as a one off be OK or will I struggle to get him back on the boob?
