ds 10mo is growing out of his latest growbag and it makes sense to get him in pj's (would be so much cheaper) - what do you use as a quilt? had him in fleecey baby grow last couple of nights with a sheet and blanket over him but he keeps waking up as kicking off the covers (thats why he went into a growbag at 6 weeks!) any ideas? I can't keep him in growbags forever
