Delay in gross motor skill at 10 month review

I think I am looking for some reassurance as this is causing me terrible anxiety.I have a 10 month old that has been slightly delayed in his gross motor skills, but nothing I thought was serious. He was steadily sitting by himself at 7 months and rolling around at 5 months. He’s always been a happy and content baby with very good head control so I didn’t see any issue with it.He’s currently not properly crawling. He started commando crawling at about 9 months and is happily getting around this way ever since. He’s walking with us holding his hands and leaning against furniture, but not pulling himself up (although he does try).At the review yesterday the health visitor considered all these things a problem and would like a further review in 3 months time. She thinks he should be crawling by now, standing against furniture and picking things off the floor while doing it. She was also not happy about the fact that he didn’t hand a toy over when you ask him.He is quite a big boy and always thought that it could be why it took him slightly longer, but now I’m doubting everything.I went into the review happy and confident and have left an anxious mess as the health visitor couldn’t or chose not to explain the consequences of not meeting these milestones on time. This has caused me to spend the evening googling every possible scenario.I would really appreciate any input or knowledge you might have of similar situations. via /r/Parenting https://ift.tt/2pg4lWd
