Hi everyone, FTM so prob a daft question but now the weather is getting warmer what should I be dressing my 4 month old son in? It's due to be 20-22c here over the next few days. Is that warm enough for shorts and tshirt? When do you ditch the vests underneath? He will of course be kept in the shade when outside so won't be in the direct sunlight and a hat worn! Thanks for any advice for a complete novice!!!
