Going over seas to visit family. MIL is being great and organising lots of stuff for us as it is not feasible for us to take things- e.g. Car seat, a bouncy chair (his favourite thing) and cot amongst other things. However I have asked her to send dims for the mattress, so we could get a new one to put in the cot. It would seem to be an unusual size so I can't find one. Am I being unreasonable to suggest that we keep that borrowed cot as a downstairs play area where she has dogs (as do we so no dog issue but these dogs have never encountered a baby before) and just order a travel cot with mattress so we know it is new and it all fits together for upstairs for actual sleeping? Or am I over thinking the whole thing and should just use this borrowed travel cot and mattress?
Our history is 4 miscarriages for me, with my older sibling lost to SIDs; I know that has no direct medical bearing for this baby but just to explain some anxiety.
