my first daugther went into her big bed for day sleeps just after she turned two (i had the same safety rail) by the time DD#2 was born (she was 2yrs 4 mths) she was sleeping in it t night time too, i didn't want her to feel like she was being kicked out once baby was born IYKWIM?

i guess it depends also on if you think she will climb out?

i think a porta cot would be annoying for a NB, so far to bend down to pick them up, unless you have the bassinet insert for it?
