I have not had to address all of the concerns that you are having but my Ashley did not start walking until after her 1st Birthday. Rolling over and tummy time were not there either. She hated being on her tummy. She did roll over 1 or 2 times before her 1st birthday but she did not master it until later on , around 14-15 months, now she is a pro. I realized I could not do anything to get her to do the steps fatser, I tried. She only will do things when she is ready, not when I am. Boy, I H. that doesn't last for long. I H. this helps. Every child is different and they do things at their own pace.
