My nearly 2 year old won’t stop standing/knelling on my stomach I’m 15 weeks pregnant and it’s something he’s always done when he climbs up onto me or when we cuddle I’m worried about my unborn baby ? We try to tell him to stop and explain there’s a baby in mummy’s tummy but he doesn’t understand I don’t want him to hurt his brother or sister or cause long term damage to the baby but also every time I take him away or put him down he runs away and hides I do it Nicely and never shout at him about it but he’s starting to not wanting to come near me or my stomach ??
