Some opinions please. My DD will be 6 in a few weeks. She's an August baby and therefore almost the youngest in her year, she's also very petite, sucks her thumb and is young-minded in herself. She often wants to act like a baby, have me carry her around, sometimes speaks baby babble, gets me to pretend she's in my tummy and dicks around in the mornings so I end up getting her dressed so we can get out of the door. My eldest was always more self-contained and at 6 was getting herself dressed, tidying her room, clipping herself into her car seat; all things which my youngest refuses to do. We won't be having any more children and if I' m honest I do enjoy treating her like a baby a bit as she'll be my last.
Anyway, she's come home from school upset a few times saying that people call her baby. She's a little bugger as she does solicit this when it suits her (she gets the Year 6 girls at school to pick her up
) and I had a stern word with myself that I wasn't helping and should stop this 'baby game'. I told her this yesterday and she absolutely broke her heart, genuine deep sobs. Cue me feeling guilty. She said this morning that she's worried about not being clever enough for Year 2 SATS next year
She will though 
On the one hand I think if that's what she wants to do I should just go with it; if that's what she wants to explore as she develops so be it. On the other hand, I wonder if I'm holding her back and should discourage it kindly.
Would appreciate any advice or perspectives.
