At around 6 months your baby will probably learn to sit. I use the word 'around' loosely in that it can be a lot later than this and occasionally a bit earlier. Before they learn to crawl it gives us a chance to get some great sitting up poses and also makes it fairly simple to get closeups of their features - which are growing and changing so fast.
Crawlers and Cruisers
You've spent a good part of the year watching, waiting and encouraging them to get mobile and now that they are... you wish they'd sit still for just 5 minutes. Crawling is one of the biggest milestones in the first year and it's a lovely one to catch on camera. When they start to cruise, we can prop them up on different objects and keep them a bit more still for closeups. A big enough basket will have them cruising round in circles for ages!
