This is a good point and may explain why he's not having anything more solid yet.My son was a chunk too, he had fat rolls that made him look like he was screwed together, even on his wrists he also had a wodge of fat above his nose that made him look permanently frowning. He didn’t sit unaided until almost 8 months. This was when he started BLW as he needed that milestone first. He was also exclusively breastfed and the HV kept saying “are you sure he’s not having formula” every time she weighed him. When I asked her why she was accusing me of slipping him bottles she said she wasn’t. I said well I doubt he’s creeping out of his cot in the early hours and scoring SMA on street corners. Our relationship was never going to be good this is why I don’t speculate on Ronnies development. They’re all different. My son was lazy and did everything in his own time, he’s still like that now at 6. My daughters were both tiny at birth, the largest being 5lb 3 (also both sections, the 9lb boy was natural. How’s that for cruel ) and we’re both raring to go. Like you say, all babies are different. He’ll soon catch up and if not as he has his developmental checks, I don’t recall what ages they are now, if required anything will be flagged up and they’ll be supporter accordingly.
As much as I dislike the Hinch brand I like to think that behind closed doors, or rather away from the gram, she’s a lot more attentive than she appears on it.
I do think it is harder for bigger babies aswell. My daughter ended up being tiny so it was easy to just throw herself around.
My boy was 9lbs 7 born (in his sac) I feel your pain!!! I dread to think how big the next would be if we decide to have another. My daughter was 8lb 6 lol!
