You don't have to do every day, as I said you could maybe do every few days.
Plus if you're over ambitious (I'm very much guilty of this myself!) and set yourself goals that are too big of a change for you and gonna knacker you then you're more likely to give up, cos you'll get fed up!
Achievable goals are much better to aim for and build upon.
Eg Try 2-3 times a week at the moment for a few weeks, then every other day, then weekdays and have a break at weekend etc
I'm very sceptical of anyone who claims to ALWAYS feed their child vegan organic home cooked from scratch meals every meal time! 
Be realistic, find "shortcuts" that work for you like batch cooking, using healthier convenience foods etc
I'm vegetarian all my adult life and raised dd as a single mum while at times working/studying/running around like a blue arsed fly!
MOST of the time it was healthy, freshly cooked meals or ones that had been freshly cooked then frozen and used as leftovers but SOMETIMES I used jars, ready made items, jars/tins/packets there's nothing wrong in that as long as you are careful and understand nutritional info etc
The main thing you have to watch is salt as that can be dangerous to a little one in excess.
My dd is approx same age as the "child of our time" tv show kids and I STILL remember the weaning episode where there was one family where both parents had learning disabilities. They were lovely people but they weren't getting the support they really needed and iirc they'd also been raised in care themselves
While filming the CREW (I think one was a recent parent themselves) noticed they made a meal with a lot of salt added in various forms - what I mean is not just a little seasoning but they were using a packet sauce, plus stock cubes etc - when the crew spoke up was when they portioned off a little to blend/mash to give to their young baby.
NOBODY had told them about the dangers of salt, all the hcps and support workers had just assumed they KNEW and had simply said to them "just feed baby what you eat just blend or mash it" without actually asking them what they ate, how they cooked etc.
There's been a few cases in the news over the years of babies hospitalised or dying from salt toxicity. Scary.
But the main thing aside from health side I think is aiming to make your life as easy in possibly in the future. It's hard enough raising kids without having to deal with fussy ones.
My own dd has certain foods she can't eat which at this stage I thought was fussiness. Turns out she had a disability she was born with but which wasn't dx until she was about to start high school and certain foods are an irritant to her or upset her stomach but she couldn't say this when she was little
When we got the dx and started reading lots so so many things about her "preferences" around food, meal times, amounts etc made sense even her metabolism (very high! Despite her liking oily/fatty foods - turns out she was subconsciously "self medicating" with her food choices)
I was raised on "meat and 2 veg" but seasonally and always a variety.
I stupidly never really thought about or appreciated the thought, time and effort mum put into feeding us.
I'm a Scot and parents are from VERY poor backgrounds and there was never loads of money to go around but she always fed us well.
When I did home ec at high school and learned about why eating seasonally, eating a variety, why we eat all the food groups etc was important I talked to mum as I then NOTICED eg it was a different veg every night even if potatoes 3 nights in a row. I NOTICED the "menu" changed in autumn from the "spring/summer menu" (it was a bit "if it's sausages it must be Tuesday") , that she worried if we didn't finish it.
As a Scots family living outside Scotland mostly we were also seen as a bit "weird" as she made a lot from scratch when the era (70's/80's) was very much embracing convenience foods. She regarded them with much suspicion and she was mostly right!
She always has a big pan of home made soup on the go even now when it's just her and dad.
It's one of my strongest childhood memories coming in from school and smelling the soup heating up. Because she gave us it as a healthy, filling but cheap after school "snack" - mug of soup, roll or slice of bread and butter (always real butter!) to "do us" until dinner time.
Dad is very ill and she is his carer and soup is one thing he can always eat even if his appetite is virtually non existent and he can barely swallow, so she makes it packed with nutrition.
It's a habit she has passed on to all 3 dc, we tend not to keep the pan on the go on the hob but most weeks we make a batch of soup to freeze. We have different preferences, mine are obviously just veg and I like it thick but blended, sister likes minestrone type or with rice in etc, bro likes a good "stand your spoon in it" broth with lentils and pearl barley, he's a police officer and has found its perfect for when he's come off a long shift and he can't be arsed cooking but needs filling up.
Find recipes (not just for soup ) you find quick and easy and make them your staples, one pot wonders are my favourites as I hate making more washing up than is necessary 
that's another benefit of batch cooking! Make enough casserole in a large oven dish for 3-4 meals and you've only used one "pot" to wash up for several meals!
I'm disabled now and struggle with peeling and chopping you can get pretty much any veg ready peeled/cut now! Eg if I'm making a carrot soup I'll buy a big bag of carrot batons rather than struggling standing peeling and chopping carrots (plus I'd probably cut myself!),
Stir fry veg, squash, sweet potato, onions, celery, even normal potato you can buy ready peeled and prepped.
Frozen veg is good too and can be better nutritionally than fresh in some cases.
I swear by frozen diced onion! So much easier than faffing with fresh onions and my eyes go nuts more than most with the crying thing! Plus as it's just me a bag can last me ages even though I use it as a base for most recipes.
Sorry I've gone on a bit there. Hope some of it is of use and makes things a bit easier for you and baby
