There is a mistake in the published pattern for the "Sherbet Stripes Hat" in Tunisian Crochet for Baby, which could result in your hat being too large. The correct instructions are below. I apologize for the error.
CORRECTION to initial chain count: For size Newborn, chain 60. For size Baby, chain 70. Stitch counts will be 60 (70) up to crown shaping.
Here are the stitch counts for Newborn crown shaping: Row 1: 50 lps on hook (there will be no extra sts after pattern repeat) Row 2: 50 Row 3: 40 lps on hook (there will be no extra sts after pattern repeat) Row 4: 40 Row 5: 30 (there will be no extra sts after pattern repeat) Row 6: 30 Row 7: 20 lps on hook (there will be no extra sts after pattern repeat) Row 8: 20 Row 9: 11 lps on hook (Tks in final st) Row 10: 11 Row 11: 6 lps on hook (there will be no extra sts after pattern repeat. Fasten off, leaving long tail.
Here are the stitch counts for Baby crown shaping: Row 1: 59 lps (Tks in each of final 4 sts) Row 2: 59 Row 3: 48 lps (Tks in each of final 4 sts) Row 4: 48 Row 5: 36 lps on hook (there will be no extra sts after pattern repeat) Row 6: 36 Row 7: 24 lps (there will be no extra sts after pattern repeat) Row 8: 24 Row 9: 13 lps (Tks in final st) Row 10: 13 Row 11: 7 (there will be no extra sts after pattern repeat) Row 12: 7.
