DD is just over 9 months and is clearly getting a little frustrated with her lack of mobility! She sits well independently, is an expert roller, can kneel for a while if put in the position, can stand for ages against the sofa if put into the position, pushes herself backwards (gets stuck under furniture!), pivots on her tummy, and reaches for her toys in a sitting position so much so that it looks like she will get into all fours.. but never quite manages it. She refuses to get onto all fours (I’ve stopped encouraging now as she gets upset!), and can’t for the life of her move forward. I almost feel she’s given up now as shes now spending less time on her front - she just rolls onto her back. I know she is technically not delayed yet, but any tips / reassurance would still be great. I’m a FTM and tend to overthink these things! She does have great fine motor skills (can pick tiny specs of food up), and loves to clap. Worth mentioned too she’s a chunky girl - haven’t had her weighed for a while but she’s a rolls for days kinda baby. :)
