14 week old is too young for independent play. Either pop baby in a carrier and carry him around, pop him in a swing, pop him down on a playmat or wait till he’s asleep to get jobs done. Independent play doesn’t start happening until around 6 months old and some children until they are older than 6 months old x
He’s too young to ‘play’ but he should be ok if you leave him on a play mat with dangly toys to just look at or try to reach where you can see him while you do the dishes. Best thing I bought at that age was a baby bjorn bouncer. He could just sit in it and watch me unload the dishwasher or whatever to start with. Then I added a toy bar for him to fiddle with and then he learnt to bounce himself which he loved! Sometimes I popped the tele on for 10 mins to keep him entertained too
A 14 week old can’t really play on their own, do you have a play-mat that you can put near you while you do the dishes? Or do them when baby is sleeping?
