Hi, Sounds like you've maybe hit the 4 months GS and it probably is time to move towards 4hr EASY (though EBF bubs often don't make it to 4hr til they're on solids - having said that, mine did, so it is possible). The NW's I'd say are probably a combination of needing to up the A time so he gets better day naps (I'd keep that one in the bjorn and try for other(s) in the cot) and needing more food to grow. The 4 months GS is enormous and can last a week but if it goes longer than that, it probably time to look at breaking a few habits gently.
