Personally (and this is just my opinion, please don't shoot me for it
), I say forget the bought stuff and do your own. Don't bother with baby rice, it's bland and completely tasteless, and baby may then struggle with 'real' food tastes after.
Charlie had pureed carrot as his first taste, and he loved it. Remember though, that at this age, it's only a taste and getting used to taking food from a spoon, it's not meant to me a meal. Puree's are the easiest things to do. Just boil/steam some veg, then use a hand blander (about a fiver from Asda) and a bit of the cooking liquor and whizz till smooth. And ice-cube tray is great at Caitlin's young age, and she'll only need one cube per meal. Veg to puree are things like carrot, butternut squash, parsnip, cauliflower, peas, broccoli, swede. I'd make them in one batch, freeze, then remove from the trays and bag and label. As Charlie got older, I'd mix 2 cubes together (carrot and parsnip, etc). Then I started adding a bit of dairy and do things like cauli cheese. And as LO gets older, you just whizz less to leave a few lumps.
Blimey, I've gone on - sounds like I was preaching!!!!
Wobbles - if you want to give this a go, I've got some Annabelle Carmel freezing trays (like larger wobbly icecube trays) if you want to borrow them. I can bring them to the baby show if you want?
