Recently my 21 month old DD has been tantruming when I've picked up another toddler or baby, stamping her feet, big fat tears, really upset! She's a complete mummy's girl, but very independent and happy to play with other adults and children. Today we were at a playgroup, she was having a lovely time going off and playing, I put my friend's 10 month old on my knee while she ran his older sister to the loo, and DD kicked off! Same again later when one of her little friends came and sat on my knee. Several other examples over last month.
Is this a normal stage and will it get better? As we are thinking of TTC again next year!
