Products!

Look on craigslist or ebay for a bath ring. They don't make them anymore because too many babies were left unsupervised in the tub, but you should be able to find one for $5 from someone else.

My younger son is on the small side and at that age fit fine in his baby tub we had a fisher price one after that we moved him to a tub seat only because he wouldn't sit in the tub he kept standing. My oldest used one for awhile from about 6 months up he was a big boy though and out grew the baby tub rather quickly. If you are worried he will be to wobbly in the tub put him in the kitchen sink they are perfect for babies.

the "Eurobath" is good... my kids could still fit it even when toddlers.
Its made for babies and toddlers. Just look online for it.
I really loved it.

Adding This: YES, the Eurobath will fit in a standard size bathtub.
My kids were big for t heir ages... and they fit in it even when they became 2 years old. I love the Eurobath!

We used the kitchen sink for its size and the convenience of the spray hose. We also used a bath ring to hold our child upright - it is a lot smaller than a baby tub so it's easy to store.

Look at this product. Is an inflatable inlay for your tub that will protect your baby. Of course you can not leave unattended your baby in the water at any time.

I hope this helps.

If you have a bumbo seat you can stick it in the tub and wash him in that. I wouldn't invest in too much of a grinder because the babyfood stage is so short that it likely won't pay off. I just got a really fine mesh sieve and pushed stuff through it with a rubber scraper (I did see a cool grinder that steams and purees at the same time, if my comment didn't disuade you - but I don't know what it's called).

We used to live in a small condo so we never used a baby tub. I just got one of those bath bear sponges and put it on the bottom of the tub, then only filled the tub up to about the top of the bear. Once they can sit up you can just put them in the tub and just supervise closely. Once, when I was at my mom's and did not have the bath bear we just put a hand towel on the bottom of the tub so that it would be soft and she wouldn't slide around and it worked just fine.

it will save your knees and has storage in it and you can tuck it next to the toilet or behind the door when not in use.

I have a Eurobath and love it, but it isn't very compact in terms of storage and it's better for smaller babies. I just retired mine when my 9 month old tried to stand up in it and switched to the Safety 1st Bath Seat (http://www.safety1st.com/usa/eng/Products/Child-Care/Bath.... It will help your son sit safely while you bathe him and you will be able to use it for many months.
As for food processors, I just use my Kitchenaid food processor and a food mill (any kind) for the tough stuff like peas and corn. I've made all my daughter's food this way and haven't needed anything other than those two items.
Good luck!
