Are they tired signs, or boredom signs ??
I find Sam gets grizzly and fidgety after some play time on her mat, or sitting in her FP swing....i have to change her scenery and give her new toys to play with - she gets bored !!!!. Sam cannot sit up unsupported, so obv cannot crawl, it must be frustrating for her seeing all whats going on around her and not being able to explore, touch , feel.....sorry, rambling now.
