My little girl was 10 months old on 6/11 due 18th. She is showing no interest in crawling at all. She sits well, can roll in fact that’s how she travels she roll to things she wants. She does like a swimming type of action on the tummy but only in circles or semi circles no forwards or backwards. She will push off her feet ( when held up but not stay on them for more than a few seconds), she has started to rock while sitting so I don’t know if she going to bum shuffle? She very lazy and rolling works for her so don’t think she interested in doing otherwise. I wouldn’t worry crawling is not considered a milestone as some baby’s skip it. My twin brothers daughter never crawled they could walk out the room and leave her at the age of 1 and she’d still be sat in the same position playing. Then one days she just started pulling herself up and waking. She grew up missing no other milestones and was perfectly fine. She’s now 8 and can crawl haha even though she didn’t do it as a baby.
Mine is 9 months and I think will skip crawling entirely. She has always been very firm on her feet and since about 7.5 months has been walking with our support. She’s got really good just not got the balance yet so we have to help her. Crawling tho, nothing. She’s never rolled either. On her tummy she screams within a couple of mins max. Doesn’t even make a vague attempt. Can pull up if to stand if put in position but won’t get there herself. Been sitting unaided since 5.5 months. They are all so different I wouldn’t worry.
Yes, my LO is the same! Weirdly born 6/1 and due 26th so really similar to you! He’s moving backward and round in a circle but no forward crawling and not much interest being on his feet - I’m trying to not worry I think he’ll suddenly just do it one day and I’ll be shocked
