I know that young babies have the startle reflex, mine did too and it used to wake her constantly. My issue now though is that at 8 month she waves her arms around like a crazed maniac and I'm not sure whether this is normal. It's usually when she's happy/excited but it's like she has no control over them. She always does it when eating too which means she never gets anything into her mouth as they just end u scattered everywhere. She also does it when the spoon comes near her mouth and sends things flying!
This may be a very silly question but is this normal? All other LO's I know of this age don't do it!
