Kids with close bdays

Anyone have kids with birthdays the same week or very close together within a couple of weeks? We are trying for a second baby and I’m hesitant to try in January because that’s when we got pregnant with our first baby (15 mons old right now). I don’t necessarily want to hold off another month since we’ve been trying for a couple already but also a little worried if we have another with a birthday that close if they would hate it 🥴 am I overthinking this?
