When sitting on my lap/propped up on the play mat, LO has started constantly leaning forward trying to get onto her front. Once shes lying flat out on her front she pushes off with her legs trying to push herself along the floor, dragging her face along the mat! She doesnt move her arms and generally shouts in frustration the whole time. But as soon as I pick her up shes leaning forward trying to do it again! Is this tummy time?! Id love to know what she is trying to achieve & how best I can help/encourage her. Shes just turned 3 months. She has never shown any interest in lying on her tummy before now. Every time we tried it previously she cried. But shes always loved lying on our chests and going in her sling, and has good head control when she's upright. Any tips?! It would be great to hear what everyone else does with their LOs.
