I've been using the bath seat cushion/pillow since my boy was 1 month old. You can check out Shopee. The seat has belt tt can be attached to the sides of a baby bath tub. As long as ur baby can lift his head up during tummy time, he wld be able to sit in it comfortably. My boy now 3 months have been enjoying his bath sitting like tt 😅 https://shopee.sg/product/40263154/7435413613?smtt=0.78334957-1616661001.9
Yes or you can get the bathing net. I needed it urgently for my 1 mth old bcos the whale shaped cushion that I bought started to have dots of mold eventhough I dry drain it so I got the net from Kiddy Palace instead.
