Where to stay in St Lucia with 1.5yo

My husband and I honeymooned in St Lucia over 10yrs ago. We want to take our first family vaca there. We are looking for calm safe waters, sandy not pebble beaches, and little to no seaweed. We don’t need kid activities but do want to stay somewhere that’s welcoming to kids. Don’t care if it’s all inclusive and usually we stay places where we have a kitchen so we can choose to eat in or out. Would like to have a pool, even better if there’s a pool safe for young kids but ok if not. Budget is around 10k for the whole trip so probably 7k ish for lodging if it’s not all inclusive. Could go higher if it’s all inclusive.

Any suggestions on where to stay? We honeymooned at coconut bay which we’ve decided is a no go this time bc of the beach.
