Exactly two years apart is a perfect gap! Yeah, it’s hard in the beginning but so great for the siblings.
I echo the advice above, especially about setting sacrosanct “dates” with the older child. I also would talk to the baby and tell her, so that older child would hear, “I can’t pick you up right now, Baby, I’m playing with Larlo”. It evened out how often I had to tend to the baby.
