LO has started not sleeping as long as when he was STTN and i badly need to start sleeping more than 4-5 hours straight. I've seen baby porridge for babies down to 4 months in the supermarked and am wondering if this might be something to try when LO reaches 4 months in a few weeks? Anyone else give their LO's something other than breastmilk before bed to make them sleep longer? Either formula or porridge.. Does it even work?
