Nope, not before -- went under twice within a few weeks (MRI and then ear tubes) and language exploded in the month after.
You should also read this very comforting study in Lancet:

"363 children were randomly allocated to the awake-regional anaesthesia group and 359 to the general anaesthesia group....
"The 5-year follow-up assessments were done between March 13, 2012, and April 27, 2018....
"When multiple imputation was used to account for missing data, WPPSI-III FSIQ means appeared equivalent between the two groups in both the per-protocol analysis (adjusted mean difference for awake-regional anaesthesia minus general anaesthesia 0·23, 95% CI −2·59 to 3·06) and the intention-to-treat analysis (0·16, −2·45 to 2·78; table 3)."
Authors go on to say about other studies:
"Cohort studies have yielded mixed evidence for an association between anaesthesia in early childhood and a subsequent diagnosis of ADHD or other learning disability....In all these cohort studies, any associations found between exposure and poor outcomes could be explained by confounding. For instance, because children receive anaesthesia for surgery or invasive investigations, the condition warranting the procedure might itself be associated with increased risk of adverse neurodevelopmental outcome. Similarly, children with pre-existing but as-yet-undiagnosed behavioural problems might be at greater risk of needing the procedure."
