14 wks pregnant with second + a 2.5 yo toddler

I. Am. So. Tired. Lol My toddler is easy to talk to naman but still bfeeds at night. We co sleep so tendency is may times pa din nag bfeed siya middle of night, but no na day time. She is potty trained too. I’m a SAHM with a stay out helper/cleaner. Husband works full time. As in FULL TIME. I cook all our food and very hands on with my toddler. I’m traveling alone this coming August out of the country (will be 5 mos preggo by then), personal trip to fix some important family documents. I don’t know when I should start preparing things for the new baby. I’m a little bit just blank at this point, nausea literally just ended but still gets upset tummy most days. Ahhh I need to get my shit collected very soon. 😮‍💨
