I’m late to this party but I can’t believe Ronnie is only just crawling? Isn’t he almost 1?!
Not that unusual, kids develop at different rates. I doubt even hunch can delay that.
Re baby proofing there is only so much you can do, kids need to learn, they definitely will get hurt, aside from stair gates and not having anything harmful they could eat/poison themselves On at baby level I didn’t baby proof by homes, my kids have both survived into adulthood/teenage years just fine.
Re the loft I though it was weird about the memory corner plans, love you’ll rarely look at those photos/scrapbooks and Ronnie isn’t gonna care either. Unless you don’t get a social circle /hobby that is, without those then yes you are likely to live in the past constantly. I have to think really hard about the warnings of my two, it’s not something I look back on really. Or ever need to recall.
