I do similar to Ispy, lunch is finger foods so i do food prep while he eats in his highchair. If I need to cook tea I throw fruit sticks at him after his main course and he entertains himself.
J has just started proper napping this week. He has 1-2h around 10 and 1-2 around 2. I feel like I have loads of spare time. I lay next to him in my bed and he falls asleep within 10 mins as long as I've timed it right for when he's tired.
Jamie is a food demon! He's making up for 6 months of force feeding him milk which he's always hated. Today he's done a full weetabix with whole milk, a boiled egg, broccoli, pepper and hot cross bun, cod and sweet potato, a yoghurt and 1/3 of a mango. He's been unfillable. He's still only little though. I forgot to take him to weigh in so I'll do it on Thursday instead.
