Please help...

Nay
Is anyone else going through this... I'm a mom of a 5 year old and 2 year old twins and 5 months pregnant. My 5 year old is excited about another baby but still enjoying everything... The twins one is Very independent which he has pretty much always been. The other twin is starting to attach hisself to me more and more. We were sitting outside my moms yesterday and I sat in her car (driver seat) with the door open and he started screaming bloody murder pulling on my leg telling me to get out so I get out & go to my car and do the same thing he started screaming again as if I was pulling off & leaving him... Sleeps with his leg & hand on he or I have to hold him which isn't normal... He is also starting when I take him to daycare I don't understand why it's getting this bad... No I don't know what I'm having yet but I'm 80% it's boy #4... I need help it's somewhat annoying & embarrassing... Especially when ppl say ooh that's  your fav or he's really spoiled but he just started acting this way 😤... But all of them are my brats I love them, just kinda guess he's being protective. My oldest was very welcoming of me being pregnant & his to baby brothers on the way...
