how late does your LO have their last meal of the day?
I'm very baby-lead in terms of meals - I feed when she is hungry rather than according to the time. So what time her last meal is depends on what time she has her dinner (which in turn is related to what time she has lunch and breakfast).
She sometimes has dinner as early as 3pm. In which case I'll offer supper (usually porridge) and this might be an hour before bed, or 2 hours. Whenever she gets hungry. Sometimes she doesn't have dinner until 5pm or 6pm so that would be the last meal before bed since supper wouldn't be needed.
I wasn't too bothered until I met some other mums last week with similar aged babies and they all appeared to be crawling to some extent, and one was even pulling herself up already and standing.
That's exactly why I don't make a big thing about it. KitKat - it doesn't matter. I mean, it really, really makes no difference whatsoever how mobile your child is at this age.
Babies who are crawling, standing etc are not unusual at 6 months, lots and lots of babies are. There is nothing special or "early" about mobility at this age, just the normal spectrum.
Likewise it is nothing to worry about having a baby who is not moving by 7 or 8 months, this is equally as normal and not unusual. There is nothing "late" about this mobility, it is just a reflection of normal spectrum.
When you're out at baby groups, you are much more likely to be coming across the mobile babies, because that's when you need a baby group. So mathematically, not a representative sample. You also get very boastful Mums who like to show off through their children.
