We used the mantra 'under one it's just for Fun' so don't put any pressure on yourself. We just put DS in the high chair whenever we were eating and gave him a little bit of something that we had. He loved mashed banana and yoghurt for breakfast, when he got a bit bigger a few Cheerios or rice Krispies dry on the tray were a great way of him entertaining himself.
At lunch we would offer soup, mash, pouch or anything we were eating that was soft. Bits of cheese, ham, some cooked mixed veg, pieces of cooked pasta.
Then we would offer him some tea at about 4pm. Stuck to normal milk times.
If he ate that was cool, if it all went on the floor to the dogs that was cool too.
He is now 14 months and eats everything. Especially at nursery where they feed them a quite exotic range of foods. He is not a fussy or picky eater at all. Loves things like filled pasta, hummus, falafel, egg mayo sandwiches, jacket potato with tuna, roast dinner etc ...he can eat a piece of fruit like an apple, pear or banana whole even with just 4 teeth. Absolutely loves blueberries and raspberries, strawberries etc.
I liked the Holly Willoughby book which I got from the library. I didn't do any of the receipes out of it but liked the schedules and blw ideas it had. It was great for age related guidance and reassurance.
But until they are one really just do whatever suits you best as long as the milk situation is all a-ok. The more relaxed about it you are the more relaxed they will be. When DS was bigger we did try all the ready made baby snacks in aldi and Lidl for something easy when out and about. Some of them he liked, some not so much. We liked the Heinz range of toddler tray meals, which are often on offer in asda...we used them when what we were eating was too crunchy, sharp or spicy, or needed more teeth than he had, or if we were eating later. He liked those better than stage 2 pouches because they had texture and wider range of flavour. He would eat half of one for lunch and the other half for dinner.
We got some basic all in one cover alls with sleeves from eBay and I then popped a soft small cotton bib over the top to stop anything going down inside the cover all. I got some lovely soft microfibre cloths from the pound shop to pop under the tap warm to wipe his face and fingers and then clean the tray with and it just goes straight into the wash. Loads better than trying to clean up with baby wipes.
