Advice for 2 under 2?

I have a ~6 month old and I am ~6 weeks pregnant so the oldest will be ~14 months when the little one is born.

Any advice for 2 under 2, specifically for little ones like 12-16 months apart?

I am feeling good about it, I just worry about like if I have to leave the room to like use the bathroom if they have to be in separate enclosed areas and like little things like that. Things I probably shouldn’t worry about now, but I like to be prepared.

I already from the beginning I am *trying* to train my 6 month old to be more “independent” (ie he feeds himself the bottle + he starting to practice feeding himself food) and develop “coping skills” (we do “deep breaths” where I count and pat his belly until he calms down a bit). But I also want to make sure I am still prepared to give him the attention he deserves.

I also have family support for the first ~5 weeks post-partum planned mostly to help with the older one.

Not sure exactly what I am looking for, but I am open to all suggestions or favorite advice/insight! Also open to words of reassurance + positivity because I am tired of hearing “you’re going to have your hands full” jaja.
