hello there mummy! i understand your worries esp in the first trimester. im in my 3rd trimester now w a 2YO too.. my daughter only wants me to feed, change, and do everything for her and dw anyone else.
at first it was abit tough, but i try to talk to her about the baby nicely and how i need other ppl help.
she cried and fuss about it at first but so far she is ok now w my hubby changing, and feeding her.
occasionally i still need to carry her, but at times if i really cant (bc nw at the last tri, everywhere is aching + breathless), ill just put her down and coax/distract her with other things.
try to take it easy in yr 1st tri ok mummy. i was advised by gynae not to carry my 2YO in the 1st tri, only after that i am more confident
