We are at same dilemea as DS will be 18 months when 2nd bub born.

Bub will go into bassinett for 3 or 4 months and then will see whether will borrow a 2nd cot or put DS into a bed.

Currently I think we will be borrowing a cot as DS is still all over cot and I dont think he would be safe in a bed even with a rail as he ends up at top of cot and side ways.

Our porta cot has 2 levels so isnt too low and change thing is also not too low but wouldnt use for long term use.
