Hello , my 6 week old has just had growth spurt I think and today has been overtired and apart from not knowing what she wants she cried the house down this afternoon! She got into such a state that she started to gasp / suck air and jump, like kids do when having histerics , you know when the gasps seem to find a pattern within the crying? The crying has stopped but the little gasps / jumps, though not as frequent, haven't all together gone and she keeps waking up due to them. Has anyone experienced this and will it stop and is there anything I can do? Giving lots of cuddles anyway.
