@waterb0ttles I see a number of bug reports when I google toddler bed. Please check these and see if they are the same as your issue and if so please 'me too' the post and add helpful information if you see details in your game that would add to what's there.:
As far as the high chair, I'm not sure I'm understanding correctly what you mean by the won't go in the high chair. Do you mean they refuse to let an adult or teen put them in? What happens when occurs? Does the interaction just drop for the adult &/or the toddler? I didn't initially see any recently added highchair bugs, but I may have missed one that matches yours.
But... I can tell you I'm not much of a fan of using the evil highchair. Personally, I have had a great deal of difficulty over time with adults and teens in the home autonomously queueing up to feed the toddler in the high chair at the same time I directed another sim to and this can become a musical chairs nightmare of feeding prompts (though I believe they have improved it lately?). I've actually gotten really, really upset about this at times, in concern for my toddler who needed to eat.
My workaround? I delete the high chair. I drag a plate or platter of food from the refrigerator to the counter and have the toddler grab a serving. I put a nice, comfortable child's lounge chair in or near the kitchen and the toddler is delighted to go eat in it, on the couch, or occasionally they just sit on the floor. Everyone is happy and the toddler eats. Other good ideas for 'free feeding' toddlers is to make popcorn (it never goes bad and they can grab a serving from it) and leaving out fruit that doesn't go bad for the toddler to grab and eat. Apples are especially nice for this and make a 'happy' moodlet for the toddler. You can also drag a few spare apples into the toddler's personal inventory to direct them to eat if they're not near the kitchen.
You could make a bug report and see if others are having the same issue if you think your toddler/highchair issue is more pronounced than this?
@waterb0ttles, yes I also stopped using highchairs soon after toddlers were added to the game! 😞 High chairs are evil!!! 👿 Like @SheriGR stated, toddlers will use a couch, bed, or even the floor to eat. They also will eat at any chair that isn't pushed up against a table or desk. They will also eat on some ottomans/poofs as well!. You will be much happier if you get rid of all highchairs in the game. 😃
