My next door neighbour has a baby of 10 months and a new boyfriend who lives there 6 nights out of 7. They sit in the garden, in the dark, from getting home from work until 1am every single night drinking wine and he chain smokes. Baby is upstairs in her room. They sit out as her landlord doesnt allow smoking in the house-(meanwhile my house stinks of smoke) My concern is .....is it acceptable to leave a baby every night like that while they are drinking a couple of bottles of wine? Am i being old fashioned in that at least one adult should be in the house?
