oh, this could easily have been me.
ds is perfectly fine and warm.
he may look like he is wearing 'just' a sleepsuit, but usually has a vest, t shirt, and socks on underneath. (neglected third child wearing a mish mash of hand-me-downs
. as long as it is clean, it's fair game!)
he gets too hot in his car seat if I put a jumper on him as well, and over-heating can be very dangerous. he spends a fair bit of time in the car after dd2's school drop off (for dd1's school run), so it is important he is comfy for that.
all 3 of my children have run hot rather than cold - dd2 will skip across the playground not wearing a coat unless it is bucketing down with rain, as will dd1.
I would trust the parent (the person holding the baby
) to judge how many layers the baby needs to be wearing - after all, they are the ones best placed to judge how hot/cold the baby is.
