best baby carrier

Veronica • George Alek Jr 4/08/17💙 Layla Jae 8/16/2018💜 Currently pregnant due in November

I have a one year old son and his sister will be here in August and I want to invest in a baby carrier but I'm 5'2 and on the leaner side and want to get one that's comfortable for me and the baby also because I feel like I'll suck at the ones that just tie...help a sister out what y'all recommend lol
