Good job! Both sentences are mostly correct. Here are tiny fixes and simple explanations so they sound even better.
- Sentence 1 — original: A baby kangaroo feels good and safe inside its mum’s pouch.
- Better version: A baby kangaroo feels safe and comfortable inside its mother's pouch.
- Why? "its" (no apostrophe) means the pouch belongs to the baby kangaroo. "Mother's" or "mum's" shows the pouch belongs to the mother. You can use "mum" (British) or "mom" (American). I used "mother's" because it's a little clearer for school writing. "Feels safe and comfortable" sounds a tiny bit nicer than "feels good and safe."
- Sentence 2 — original: A mother kangaroo carries her baby in a pouch on her belly.
- Better version: A mother kangaroo carries her baby in a pouch on her tummy.
- Why? The word "carries" ends with -s because we are talking about one mother (she carries). "Her" shows the pouch belongs to the mother. "Tummy" is a child-friendly word for "belly."
Small extra tip: Watch out for "its" and "it's" —
- "its" = belongs to it (The kangaroo waved its tail.)
- "it's" = it is (It's a baby kangaroo.)
Final recommended sentences you can use:
- A baby kangaroo feels safe and comfortable inside its mother's pouch.
- A mother kangaroo carries her baby in a pouch on her tummy.
