Sleeping habits of my first born

Hi mommies! Is it okay if natutulog ang first born ko (12kgs) na nakadagan sakin? I’m currently 12 weeks pregnant. He’s breastfed for 1yr7months, and nagstop kami since naging preggy ako kaya sobrang clingy ni baby, isama pa ang teething. Sobranv worried lng n baka magkaroon ng epekto sa growth ng second baby namin.
