Life insurance - worth it?

I’m 29F and have recently had a baby. My husband (28M) and I are currently living with my parents while we look to buy a house. I am the breadwinner (when not on maternity leave!) and also out of me and my husband, am better at saving and planning finances. Having had a baby, I feel strongly that I want them both looked after if I was to die either through an illness or unexpected death (I am fit and healthy). Is life insurance worth it? Or are there alternatives I haven’t thought of? It’s something I never thought about before so know very little about it all. TIA.
