Has anyone experienced their toddler acting different now that you're pregnant? My son is 2 and a half and is doing odd things that make me wonder if he comprehends there's a baby on the way. I'm 4 weeks and my son has been throwing more fits, saying he's a baby, wanting nothing to do with my husband and I when my mom and dad are around. I haven't told my parents I'm expecting baby #2 yet but they're suspecting something is up because I hate to say it but my son is acting like a brat lately. Is this normal for toddlers to do? Has anyone experienced this?
