First time living in a flat - there’s a front door which I have to buzz to let anyone in. Wasn’t sure if it was cheeky to buzz in people with deliveries or if they’d expect me to go down? Have a 1 year old DD so it’s a hassle taking her down two flights of stairs and then back up with the deliveries. also feeling hungry and want a takeaway but can’t leave her unsupervised while I rush down
