Wa'alaikum assalam! Ehhh same sini, memang stressful kan? A few of my mum friends had this juggling act, their kids reject proper meals tapi snacks boleh habis dalam 5 minit lol. What worked for our circle is buat snack time structured (bukan free-for-all sepanjang hari) and offer meals even if dia reject, then let it go je, sometimes when mereka tengok kita chill, baru suka try. But honestly if kau risau about weight gain or nutrition, better check with the paediatrician just to be safe, sebab they can assess if ada underlying issue or kalau just picky phase ja. Hang in there, first baby memang test patience tapi nanti okay!
